INTRODUCTION
This owner's manual describes the
Fleet Power Inverter/Chargers from Heart
Interface. These units perform three distinct
functions:
Fleet Power Inverter/Chargers operate
as self-contained backup power systems,
just add batteries.
1. DC to AC power inverting.
• Fleet Power battery chargers are electroni-
cally controlled and rated:
2. Automatic transfer switching between
inverter power and incoming AC power.
3. Automatic 3-Stage Battery charging plus
manual battery equalizing.
FP 1000-12..................50 Amps DC
FP 2000-12................100 Amps DC
FP 2500-12................130 Amps DC
4. AC to DC power converter.
They are designed to rapidly and optimally
recharge either wet* or gel* cell deep-cycle
batteries. Battery charging is accomplished
in 3 automatic stages: Bulk Charge, Accep-
tance Charge and Float Charge. In addition,
using the remote control, a manually-en-
gaged Equalizing Charge cycle is possible.
• The inverters provide regulated 120 Volt
AC power and crystal controlled frequency
at 60Hz from a deep cycle battery bank in
specified watts:
FP 1000-12................1000 watts
FP 2000-12................2000 watts
FP 2500-12................2500 watts
With an external AC source connected,
the Fleet Power charger also serves the
functions of a AC to DC converter to supply
all of the DC loads which are connected to
the battery.
The output is a modified sinewave and
is compatible with appliances, tools and
other 120 VAC equipment. Momentary
surge power of three times the inverter
rating is available for starting electric mo-
tors. High efficiency insures the longest
possible battery life between recharges.
Simple, automatic operation is made
possible by the microprocessor in the Fleet
Power Inverter/Chargers. In most cases, the
unit is left on and no attention or mainte-
nance is required.
• The transfer switch allows the Fleet Power
Inverter/Chargers to be connected to an
external AC source and transfer the source
through to the loads. When disconnected,
the transfer switch allows automatic switch-
ing back to the inverter.

• Ambient Battery Temperature
• Battery Type
• Charger Mode (Auto or Controlled)
• Power Sharing
Electronic Protection
Fast acting electronic circuits protect
the inverter from extreme overloads and
short circuits. Other protection includes a
low and high battery cutoff and automatic
shutdown if over temperature occurs. The
fault condition must be eliminated before
reset will occur. Example: remove over-
load, recharge batteries or allow to cool.
Reset by cycling the power switch OFF/ON.
Circuit Breaker Protection
Fleet Power Inverter/Chargers are
circuit breaker protected.
The Fleet Power 1000 has a 12 Amp
INV/CHG circuit breaker on the front of the
unit that protects against sustained inverter
overloads over 1440 watts and the AC input
to the battery charger. The 15 Amp INPUT
circuit breaker on the unit protects the
incoming AC circuit which is transferred
through to the loads via the GFCI.
Power Sharing
When connected to shorepower or
using a generator, the battery charger and
transfer functions are engaged. A unique
power sharing feature automatically reduces
the AC consumption of the battery charger
allowing necessary AC power to the load.
This prevents the circuit breaker from trip-
ping. This feature can be adjusted using
the remote control panel. This feature is set
at the transfer rating of each unit by default.
The Fleet Power 2000 has a 25 Amp
INV/CHG circuit breaker that protects
against sustained inverter overloads over
3000 watts and the AC input to the battery
charger. .
The Fleet Power 2500 has a 30 Amp
OUTPUT circuit breaker on the unit that
protects against sustained inverter over-
loads over 3600 watts. The 30 Amp circuit
breaker protects the incoming AC leg which
feeds the battery charger.

OPERATION
Power Switch
The Power Switch is located on the
front panel. This switch controls ON/OFF
and RESET for the inverter. Expect a 3
second delay when the power switch is
turned ON before the unit is activated.
Power Switch
If the unit is connected to external AC
power, the battery charger and transfer
switch will continue to function, regardless
of the position of the switch.
When external AC power is removed
and the power switch is in the ON position,
the inverter will automatically be ON. If the
switch is in the OFF position and external
AC power is removed, the inverter will be
OFF.
Fleet Power 1000 shown.
Inverter overload protection, transfer
switching, power sharing and battery
charger regulation will all function automati-
cally.
If installed with the remote control
panel, the power switch on the unit should
be left in the OFF position. Refer to Re-
mote Control Panel, page 7.

control panel is a set of 8 dip switches
which are used to make several adjust-
ments. On the switch block, each switch is
numbered . . .1 through 8 and the ON posi-
tion is indicated. The switch settings can be
changed at any time, even while the unit is
operating. Following is a discussion of
each adjustment. Refer to the table on
page 11 for dip switch programming.
SWITCH #2 & #3 - Battery Type Gel cell
and wet cell batteries have slightly different
charge voltage requirements. Optimum
battery charging is temperature dependent.
For these reasons, the dip switches allow
four different battery charger voltage set
points, depending on battery type and
ambient temperature:

tion. With the switch turned ON, it allows
the power ON/OFF switch on the front of the
remote to control the battery charger as well
as the inverter.

SWITCH 1 - Manual Equalizing Cy-
cling this switch ON for 1 second, then OFF,
will initiate an equalizing charge cycle. The
battery charger must be engaged before
cycling the switch. The dip switch must
always be returned to the OFF position.
If it is left ON, an equalizing charge cycle
will initiate every time the charger is
engaged - this could cause battery dam-
age.
SWITCH #5 & #6 - Not used for adjust-
ments.
SWITCH #7 & #8 - Power Sharing These
switches should be set to match the value of
the circuit breaker which protects the incom-
ing AC power. They may also limit the
output current from the battery charger.
The equalizing cycle is timed to last 8
hours from the time the switch is cycled, at
which point the charger resumes normal
charging in the float stage.

batteries.
Dip Switch Status
You can check the position of the dip
switches by quickly cycling the power switch
OFF/ON twice. The DC Volts bargraph will
cease to display battery voltage and will
indicate the settings of each dip switch. In
this mode the bottom LED will illuminate if
switch 1 is on; the second LED will illumi-
nate if switch 2 is on, etc. Dip switch set-
tings are indicated for 10 seconds after
which time the display returns to indicating
battery voltage.
Factory default settings for all dip
switches are in the Off position.
Remote Control Wiring
The remote control panel is supplied
with 25 or 50 ft. of telephone cable. The
cable supplied may be 6 conductor, how-
ever, only 4 conductor is required. You may
buy standard 4 conductor telephone cable
and run up to 50 ft., if desired. Use only a
single length of telephone wire, do not
splice.

BATTERIES
It should be noted that high antimony
deep-cycle batteries will give off gas as a
natural result of charging and will experi-
ence some water loss. It is very important
that the electrolyte level be checked
frequently and topped off with distilled
water when necessary. Never allow the
tops of the plates to be exposed to air, as
contamination of the cell will result. Keep-
ing the tops of batteries clean will reduce
self-discharging. Always provide ventilation
for the battery storage compartment.
Do not use car batteries or engine
BATTERY TYPES
starting batteries of any kind with your
inverter/charger. Beware of any battery that
is rated in Cold Cranking Amps (CCA). This
is a rating which applies only to engine
starting batteries. In general, most wet cell
batteries that are described as hybrid bat-
teries, suitable for either engine starting or
deep-cycle applications, are a compromise
and will give limited life if deeply dis-
charged.
Use only deep-cycle batteries with your
Fleet Power Inverter/Charger. These fall
into two broad categories, wet cell and gel
cell.
Wet Cell Batteries
True deep-cycle wet cell batteries are
characterized by relatively thick plates that
are alloyed with antimony.
Common marine/RV deep-cycle
batteries are acceptable. However, golf
cart batteries have better performance and
life. They are 6 Volt batteries that must be
used in series pairs. High quality marine
deep-cycle batteries offer good perfor-
mance and are available in a wide variety
of sizes. Floor sweeper, fork lift or large 2
Volt cells can also offer excellent perfor-
mance, if their large size can be accommo-
dated.
Beware of 8-D starting batteries that
are commonly used for starting diesel en-
gines. These batteries are not deep-cycle.

90-0115-00
10/97 Fltman.pm65
BATTERIES
Beware of so-called maintenance-
free batteries. These batteries have cal-
cium alloyed with the lead and hold the
liquid electrolyte in a sponge-like material.
They are sealed and water cannot be
added. Do no confuse them with true gel
cell batteries, they will not hold up to deep
discharging.
The features of the gel cell batteries
solve many common problems. Cycle life is
high, even under constant deep discharg-
ing.
BATTERY INTERCONNECTION
In most cases you will be using a bank
of two or more batteries with your inverter/
charger. You may connect batteries to-
gether in two configurations, series and
parallel.
Gel Cell Batteries
Gel cell batteries are lead-acid batter-
ies similar in many ways to the common wet
cell battery, but differences in the chemistry
and construction provide some unique
features.
Series
Connecting 2 batteries in series will
double the voltage of the battery bank. For
instance, two 6 Volt batteries connected in
series will produce 12 Volts. The Amp-hour
No Maintenance - There is no need to
add water and the tops of the batteries stay capacity of the battery bank will be the

any position and may be used without a
battery box.
same as each individual battery. Example,
two 6 Volt 220 Amp-hour batteries in series
will produce on 12 Volt 220 Amp-hour bat-
tery bank.
Low Self-Discharging - Unlike wet cell
batteries, the gel cell will hold its charge for
months if left sitting with no load and no
float charge. They can be stored without a
constant float charge and without fear of
freezing.
-
-
+
Low Internal Resistance - The result
of low internal resistance is a higher battery
voltage under load, which will result in
better inverter performance on demanding
high power loads. In addition, this allows
the gel cell to accept a high rate of charge,
a plus for rapid recharging.

BATTERIES
Parallel
Always use proper terminals for your
interconnecting battery cables which are
appropriate to handle the current.
Connecting 2 batteries in parallel will
double the Amp-hour rating of the battery
bank, while the voltage will be the same as
each individual battery. Example, two 12
Volt 105 Amp-hour batteries in parallel will
produce one 12 Volt 210 Amp-hour battery
bank.
Battery Bank Ratings and Sizing
Deep-cycle batteries are usually rated
in Amp-hours. The Amp-hour rating is
based on a 20 hour discharge cycle, there-
fore, a 100 Amp-hour battery can deliver 5
Amps for 20 hours. If the discharge rate is
greater than 5 Amps, the available Amp-
hours are decreased. If the load is in-
creased to 100 Amps, only about 45 Amp-
hours will be available at this rate of dis-
charge.
+
+
-
-
Another common rating is reserve
capacity expressed in minutes. This is
derived by placing a 25 Amp load on the
battery and measuring the time until the
battery voltage reaches 10.5 Volts.
Parallel
Only similar batteries should be
connected together in one bank. Do not
connect old and new batteries together or
wet and gel cell batteries together. In the
above drawing, the load is connected to the
positive terminal of the first battery and the
negative terminal of the last battery. This
practice helps to balance the battery bank
and is called cross connecting the battery
bank.
Deep-cycle batteries can be discharged
about 80% before permanent damage
occurs, though shallower cycling will result
in much longer battery life. 50% cycling is
generally considered to be a good compro-
mise between long battery life and a rea-
sonably sized battery bank.
1 4
90-0115-00
10/97 Fltman.pm65
BATTERIES
To achieve 50% cycling you should
calculate your Amp-hour consumption
between charging cycles and use a battery
bank with twice that capacity.
To calculate Amp-hour consumption first
look at the rating plate on your AC appli-
ance or tools. Each appliance or tool will be
rated in either AC Amps or AC watts or AC
VA (Volts-Amps) apparent power. Use one
of the following formulas to calculate the DC
Amp-hour draw for a 12 Volt system:

Corin g System
In all formulas, 1.1 is the factor for
inverter efficiency.
Many electric motors have momentary
starting requirements well above their op-
erational rating. Start up watts are listed
where appropriate. Individual styles and
brands of appliances may vary.
Calculate the above for every AC
appliance or tool you intend to use on your
inverter. This will give you the total number
of Amp-hours used between recharges.
Size your battery bank using this number as
a guideline. A good rule to follow is to size
the battery bank about 2 times larger than
your total Amp-hour load requirement. Plan
on recharging when 50% discharged.

BATTERY CHARGING
Battery Charging
This presents two problems. First,
since the battery voltage does not reach the
gassing point, sulfate is left on the plates.
Second, 13.8 volts is close enough to the
gassing point that some gas will escape,
and the wet cell battery will need to be
frequently topped off with distilled water.
Conventional battery chargers also
Completely recharging wet cell deep-
cycle batteries requires the battery voltage
to be raised beyond what is known as the
gassing point. This is the voltage at which
the battery begins to bubble and gas is
given off. If charging stops short of this
point, sulfate is left on the plates and dete-
rioration of the battery begins. The gassing suffer from another inherent characteristic of
point will vary with battery temperature.
Gel cell batteries must not be charged
to their gassing point. In fact, high voltage
charging which gasses these batteries is
harmful to them. They typically require a
design, which is a tapering output. While
they will deliver their rated current into a
deeply discharged battery, as the battery
becomes charged and the voltage rises, the
output current of the charger tapers down.

remote control provides the ability to peri-
odically apply an 8-hour timed equalizing
charge.
Generally, a wet cell battery bank
should not be charged up to the gassing
point at a rate which exceeds 25% of its
capacity. In other words, a 12 volt battery
bank of 520 Amp-hours should not be
charged at over 130 Amps.

float charge stage, the full output current of
the battery charger is available to operate
any DC appliances that may be on the
system, while constantly maintaining the

The battery charger remains in the float

disconnected from incoming AC power.
Stage 2 - Acceptance Charge The
acceptance stage immediately follows the
bulk charge stage. During this stage the
battery voltage is held constant at the bulk

turers. There are no firm rules for how often
an equalizing charge should be applied, but
once a month is a good rule of thumb for
batteries which are regularly cycled, less
often for systems in only occasional use.
The equalizing charge is a timed, 8-
hour cycle. If desired, it can be ended by
interrupting the AC power to the charger at
any time during the cycle. Equalizing

switches are set in one of the two gel cell
positions, the equalizing charge voltage is
the same as the bulk charge voltage, there-
fore, equalizing is equivalent to an 8-hour
acceptance stage and is not harmful.
To limit the DC current during equaliz-
ing to less than 15 Amps, turn on dip
switches 7 and 8 before starting the equal-
ize charge. Do not operate AC loads that
are on the output of the inverter/charger
when equalizing.
1. Removal of residual sulfate. Each time
a battery is cycled (discharged and re-
charged), a small amount of sulfate is left on
the plates. Over time, this gradual build-up
of sulfate will compromise the performance
of the battery. By applying an equalizing
charge, the sulfate is returned back to the
electrolyte, raising the specific gravity and
fully exposing the active material of the
plates.
Charging Over-Discharged Batteries
Charging into a battery bank with a
terminal voltage of less than 8 Volts pre-
sents a special problem for the unit. If this
situation arises, the unit will attempt to
charge for 1 minute. If the inverter senses
excessive ripple voltage, it will shut down to
protect itself.
2. Bring all cells to the same potential.
All lead-acid batteries are made up of indi-
vidual 2 Volt cells. As the battery bank is
cycled, slight differences in the cells result
in different cell voltages, affecting the over-
all charge effectiveness. Equalizing brings
all cells up to the same voltage and the
electrolyte in each cell to the same specific
gravity.
To successfully charge an over-
discharged battery, you must remove as
much DC load as possible. Set dip
switches 7 and 8 to the ON position to limit
the amount of charge current and the result-
ing ripple voltage. After the battery voltage
has reached 10 Volts, these switches can
be set to their previous positions.
3. Mixing up of the electrolyte. Electro-
lyte in battery cells tend to separate into
layers of acid and water. The vigorous
boiling action of the battery during equaliz-
ing serves to physically mix the electrolyte.

BATTERY CHARGING
Note: If a continuous DC load in ex-
cess of the charge rate is placed on the
battery bank, eventually the battery voltage
will drop below 8 Volts and the battery
charger will shut off. This load must be
significantly reduced and the power to the
charger cycled to resume charging.
Blinking of the battery LED on the
remote control while charging is a warning
that an over-discharge is imminent and that
the DC load should be reduced.
WARNINGS
1. Do not equalize gel cell batteries
with the remote programmed for wet
cells.
2. Always monitor the equalize
charge. Provide proper ventilation for
battery fumes. Do not allow any sparks
during equalizing. If one or more cells
begin to overflow, terminate the equalize
charge.
NOTE: Equalize only after a regular
charge cycle.
3. Check and top off the battery elec-
trolyte both before and after the
equalizing charge. Do not expose the
battery plates to air. Leave the battery
caps on while equalizing.
4. Remove all loads from the DC sys-
tem before equalizing. Some DC loads
may not tolerate the high charge voltage.
5. Do not leave the equalize dip
switch in the ON position. It must be
cycled OFF and left in the OFF position.
If left ON, the unit will engage the equal-
izing cycle every time the battery charger
is engaged.

INSTALLATION
Key Installation Points
DC cable is required. The AC wire size is
dependant on potential current in the circuit.
Consult the NEC (National Electric Code)
for proper wire gauge.
The Power Switch must be turned OFF
before you begin.
1. Observe proper polarity when
connecting batteries. Reverse DC polarity
will result in damage to the unit and will void
the warranty. Use care when making the
DC connections.
5. Keep the inverter/charger out of
the elements and out of direct contact
with water or spray. Remember that the
unit is a piece of electronic equipment and
treat it accordingly.
2. Do not back-feed the AC output of
the inverter with incoming AC power. A
back-feed occurs when AC power from
shore power or generator is connected to
the output of the inverter. This will damage
the inverter and void the warranty. Remem-
ber that incoming AC must be fed only to
the AC input and never to the AC output.
Always check for AC voltage before con-
necting wires to the AC output. Do NOT
6. Mount the unit as close to the
batteries as possible but not in the pres-
ence of flammable fumes or in an enclosed
battery compartment.
7. The connectors for the remote
control and the chassis ground bonding
lug, as well as for the AC wires, are lo-
cated on the bottom of the unit. Be sure
to make these connections before bolting

ging the battery charger into the inverter.
This could occur if the unit is connected to
the entire leg of a circuit breaker panel, then
a circuit breaker on that leg is used to feed
the battery charger. This will cause the unit
to oscillate ON and OFF when the unit is in
inverter mode.
orient the unit so the switch and the circuit
breakers are facing up and the fan and
battery cables are facing down.
9. Allow several inches of clearance
around the unit and allow for a supply of
fresh air to the cooling fan. Do not block
any of the vents or louvers. The fan pulls
air from outside the unit. It blows air across
the internal components, particularly the
transformer and heat sinks, then out the
side vents.
4. Always use proper wire and con-
nectors. The proper battery cable size is
critical because considerable amperage
flows in the DC circuit. Fusing the positive

10. If installing in a system which in-
cludes an existing battery charger or con-
verter, make sure these do not operate
from the inverter output AC power. This
sets up a power loop which, due to ineffi-
ciencies, will quickly drain the batteries.
15. If multiple battery banks are to be
charged, a battery selector switch can be
installed, allowing the banks to be charged
either individually or simultaneously. A
solenoid can also be used.
11. Make sure all wiring conforms to
local and national electrical codes. If in
doubt, consult with a qualified electrician.
WARNING
Do not mount the unit in an enclosed
battery compartment. Take precautions
to keep road dirt and spray off the unit.
12. Keep the overall length of each
battery cable less than 10 feet. If needed,
attach short extension cables. Do not use
frame ground or a ground bonding system
as a current carrying conductor. Run the
negative cable directly to the battery bank.
If the positive and negative cables run
parallel to each other, twist the cables
together. This will minimize the adverse
effects of inductance.
Grounding
For safety purposes, the chassis of
the inverter/charger must be connected
to your AC ground system. The chassis
ground bonding lug is located on the bottom
of the unit. This connector can accept two
wires, the first is used to connect the unit to
AC ground, the second can be used to
connect other AC equipment to ground.
Use bare copper insulated wire, solid or
stranded. Strip one end and use a screw-
driver to secure it to the chassis ground
bonding lug. This wire will connect to the
ground in your AC electrical system, typi-
cally the vehicle chassis. Make sure the
connection is clean and tight.
13. To meet electrical codes, a fuse
must be installed in the positive battery
cable within 18 inches of the battery post.
This fuse is intended to protect the battery
and cables against a dead short circuit.
The inverter is protected internally and will
not blow a properly sized fuse.
14. DC wiring is generally very simple,
the positive and negative cables from the
inverter/charger are connected to the house
or auxiliary battery. In the case of multiple
batteries the interconnecting jumper cables
must be of the same AWG as those sup-
plied with the inverter/charger.

Output. Each side contains 3 pigtails:
black, white and green. Six wire nut con-
nectors are also provided.
This procedure will connect the chassis
of your unit to AC ground. In addition, the
AC input and AC output green wires are
connected to chassis ground. It is important
to connect these wires to the AC ground bus
in the circuit breaker panel.

Conventional metal strain reliefs are
provided. These can be replaced by plastic
strain reliefs for additional corrosion resis-
tance or 3/4 inch conduit fittings if the wiring
will be routed through the conduit.
Neutral Bonding
For safety purposes, the Fleet Power
inverter/charger unit internally bonds the AC
output neutral to the AC ground when the
unit is OFF or in the inverter mode. When
incoming AC power is applied and the
transfer switch is engaged, the internal
neutral-to- ground bond is automatically
lifted.
This means that when the vehicle is
connected to shore power, the grounding
system is connected to the shore power
ground, where neutral and earth ground are
bonded together. This technique insures
safety in all conditions and conforms to the
requirements of the NEC.
Use proper wire sizes according to the
NEC.
AC Input (Fleet Power 1000 and Fleet
Power 2000): Feed the 3 conductor AC
input wire through the strain relief and into
the AC input compartment. You should
have 6 inches of individually insulated
black, white and green wire. Strip 1/2 inch
of insulation off each conductor and connect
to the pigtails: black to black, white to white
and green to green.
AC Input (Fleet Power 2500): There
are 2 options for configuring the AC input to
the Fleet Power 2500.

The AC wires route through the holes in
the bottom of the unit. Use a screwdriver to
remove the screws which secure the AC
wiring compartment cover plate. Inside, the
compartment is divided into 2 sections, one
labeled AC Input, the other labeled AC
charger may be fed separately from the
transfer input which feeds the AC loads. In
this case, connect one 30 Amp feed to the
charger pigtails and another 30 Amp feed to
the transfer switch input.
Connecting the feeds in this way bal-
ances the AC loads when 2 legs of incoming

wires.
WARNING
If you are not connecting the hardwire
output wires (Fleet Power 2000 only), make
certain they can not cause a short circuit to
the wiring compartment. Tug firmly on each
connection to make sure they are secure.
Check these connections first if the unit is
not operating properly.
Do not connect incoming AC from any
source to the AC output of the inverter/
charger. This is known as back-feeding
and will damage the unit and void the
warranty.
Carefully tuck the wires into the AC
wiring compartment. Replace cover plate.
occur when power is applied to both inputs.
The charger can draw up to 27 Amps on
one leg of power and the transfer switch can
pass up to 30 Amps from the other leg of
power.
Single Input: Both the battery charger
and the transfer switch may be fed from the
same AC input. In this case, connect both
pigtails together, black to black, white to
white and green to green.
This allows up to 60 Amps of AC power
to be brought in on a single cable. Up to 30
Amps is available to the loads, with the
balance available to power the battery
charger. A single cable should be protected
by a 60 Amp breaker or smaller, and 6
gauge wire should be used.
Ground Fault Circuit Interrupters
In order to conform to the NEC, certain
branch circuits must be equipped with a
Ground Fault Circuit Interrupter (GFCI).
Please consult the code or a qualified
electrician for details. Any such branch
circuit must be protected by a circuit
breaker consistent with the GFCI rating.
Underwriters Laboratories has tested the
following GFCI, and its use is recom-
mended. Receptacle Type:
Pass & Seymour
Catalog Number 1591-RW
Rated: 15 Amps at 120 Volts AC
Fleet Power 1000 and 2000 inverter/
chargers provide an integral GFCI outlet
which is protected by a circuit breaker. This
GFCI outlet does not protect the hardwire
AC output. The hardwire AC output is
protected by a non-GFCI circuit breaker on
the Fleet Power 2000 only. The first outlet
from the hardwire output should be GFCI
protected to comply with applicable codes
and standards.
AC Output: On the Fleet Power 1000,
AC output is available at the GFCI outlet
mounted on the unit. On the Fleet Power
2000, AC output is available at both the
GFCI outlet and at the AC output compart-
ment. The AC output for the Fleet Power
2500 is available at the AC output compart-
ment only. When installing the Fleet Power
2000 and 2500, feed the 3 conductor AC
output wire through the strain relief and

outlets. Push the RESET back in and
reconnect the appliances one at a time. A
defective appliance which trips the GFCI
should be repaired at once.
If the RESET button will not stay in
after all appliances have been disconnected
from the circuit, the GFCI outlet has failed.
If the RESET button does not pop out
when the TEST button is pressed, protec-
tion is lost. Do not use.
WARNING
Persons with heart problems or other
conditions which make them susceptible to
electric shock may still be injured by

your ground fault circuit interrupter at least
once a month. Test procedure:
1. Push TEST button. The RESET
button will pop out. Power is now ON or

Remote Control Wiring
The remote control is supplied with a
25 or 50 foot section of telephone cable for
connection to the unit. Simply plug one end
of the cable into the remote connector on
the bottom of the unit labeled remote and
the other end into the connector on the back
of the remote control panel.
Routing the remote cable away from AC
and DC wires will minimize the potential for
interference which may affect the LED
bargraphs.
2 7
90-0115-00
10/97 Fltman.pm65
INSTALLATION
The remote control cable can be ex-
tended up to 50 feet if required. Use stan-
dard 4 or 6 conductor telephone cable. Use
a single length cable with no connectors or
in-line splices. If phone cable is left over,
coil it up and store it in an area away from
AC equipment to prevent electrical interfer-
ence.
The negative cable should be con-
nected directly to the negative post of the
battery bank or the ground side of a current
shunt. Do not use the vehicle frame as the
negative conductor. Tighten securely.
The positive battery cable must be
fused and connected to the positive post of
the battery bank, or through a selector
switch to one or more battery banks.
A spark may be generated when the
final battery connection is made. This is
normal and do not be alarmed, however, do
not make the final connection in the pres-
ence of flammable fumes.
Once the above steps have been com-
pleted the unit can be bolted down.
DC Wiring
Two battery cables are provided with
the unit. Both are black, the positive cable
has a piece of red heat shrink insulation on
the end. High current will pass through the
DC wiring. All wires must be properly sized
and all connections clean and tight.
It is recommended that the battery
cables not be lengthened, however, it is
possible to extend the cables if necessary.
Extension cables must be 00 AWG or the
same type of wire supplied with the unit, and
the total length for each battery cable must
not exceed 10 feet.
Battery Cable Fusing
A fuse is required by the NEC to pro-
tect the battery and cables. The fuse must
be installed in the positive battery cable,
within 18 inches of the battery.

things into consideration are:
1. When you unplug from shore
power, be sure to turn OFF any appli-

DC WIRING OPTIONS
WARNING
For Installations using Battery
Switches NOTE: No other DC loads
should be connected to the common on
the battery switch. This will prevent their
operation directly from charger power
when the battery switch is OFF.
DC Wiring #1 - Two Battery* System
Using Manual Battery Switch
This system is simple and effective,
providing the user with the ability to choose
between either battery for inverter use or
charging.
When charging, the battery switch is
typically left in the "All" or "Both" position so
that both batteries are charged. When
using the inverter, the inverter battery
should be selected with the battery switch.
The inverter/charger's negative battery
cable should be connected directly to the
battery that will normally supply the inverter.
A fuse should be installed in the positive
cable within 18 inches of the battery. If the
cables to the switch exceed 18 inches, each
cable will require a fuse.
DC Wiring #2 - Two Battery* System
Using an Isolator for Charging both
Batteries
This allows charging of both batteries
from an alternator, but the inverter can only
draw power from the auxiliary battery. This
prevents accidental discharge of the engine
battery by the inverter. A paralleling sole-
noid can be used in place of the isolator.

This system allows the inverter to use
either auxiliary battery. The engine battery
can always be charged by the alternator, but
cannot be discharged by the inverter. The
user can select between the two auxiliary
batteries with the battery
switch for charging or for
inverter operation.
DC Wiring #4 - Three Batteries*
Connected with Battery Switches
This allows any combination of
three battery banks to be charged
by or selected to run the inverter.
If both switches are on "all",
then all batteries are in parallel.
Batteries can be independently

1. Digital clocks either employ an internal time
base or derive their time base from the incoming
AC waveform. The frequency is usually well
regulated at 60 Hz. The clock either counts the
number of peaks in the waveform or the number
of times the waveform crosses zero volts. The
circuitry to count the zero crossing events is more
popular. The longer zero cross time of the
inverter's modified sinewave may cause double
clocking, resulting in a faster clock.

GLOSSARY
Alternating Current (AC) An electric current
that reverses direction at regular intervals.
Sources of alternating current are shore power,
generator power, inverter power or household
current.
first to the positive of the second, negative of
the second to the positive of the third, etc. If
two 6 volt batteries of 50 ampere-hours capac-
ity are connected in series, the circuit voltage is
equal to the sum of the two battery voltages, or
12 volts, and the ampere-hour capacity of the
combination is 50 ampere-hours.
Ampere (Amp, A) The unit of measure of
electron flow rate of current through a circuit.
Circuit (Parallel) A circuit which provides more
than one path for current flow. A parallel ar-
rangement of batteries (of like voltage and
capacity) would have all positive terminals
connected to a conductor and all negative
terminals connected to another conductor. If
two 12 volt batteries of 50 ampere-hour capac-
ity each are connected in parallel, the circuit
voltage is 12 volts, and the ampere-hour capac-
ity of the combination is 100 ampere-hours.
Ampere-hour (Amp-Hr., AH) A unit of measure
for a battery's electrical storage capacity, ob-
tained by multiplying the current in amperes by
the time in hours of discharge (Example: a
battery which delivers 5 amperes for 20 hours
delivers 5 amperes times 20 hours, or 100
Amp-Hr. of capacity.)
AH Capacity The ability of a fully charged
battery to deliver a specified quantity of electric-
ity (Amp-Hr., AH) at a given rate (Amp, A) over
a definite period of time (Hr.). The capacity of a
battery depends upon a number of factors such
as: active material, weight, density, adhesion to
grid, number, design and dimensions of plates,
plate spacing design of separators, specific
gravity and quantity of available electrolyte, grid
alloys, final limiting voltage, discharge rate,
temperature, internal and external resistance,
age and life of the battery (bank).
Current The rate of flow of electricity or the
movement rate of electrons along a conductor.
It is comparable to the flow of a stream of water.
The unit of measure for current is ampere.
Cycle In a battery, one discharge plus one
recharge equals one cycle.
Dip Switch A series of small switches used for
special programming of the Fleet Power in-
verter/charger. These switches are located on
the back of the Fleet Power remote panel.
AWG (American Wire Gauge) A standard
used to measure the size of wire.
Direct Current (DC) Current that flows continu-
ously in one direction such as that from batter-
ies, photovoltaics, alternators, chargers and DC
generators.
Circuit An electric circuit is the path of an
electric current. A closed circuit has a complete
path. An open circuit has a broken or discon-
nected path.
Circuit (Series) A circuit which has only one
path for the current to flow. Batteries arranged
in series are connected with the negative of the

restores capacity and mixes the electrolyte.
loads connected to the output of the inverter
are in excess of the input breaker rating.
Gel Cell Battery A type of battery that uses a
gelled electrolyte solution. These batteries are
sealed and are virtually maintenance-free. Not
all sealed batteries are the gel cell type.
Volt The unit of measure for electric potential.
Watt The unit for measuring electrical power,
i.e., the rate of doing work, in moving electrons
by or against an electric potential.
GFCI (Ground Fault Circuit Interrupter) A
protective device that rapidly de-energizes a
circuit when current to ground exceeds a prede-
termined value.
Watt-Hour (Watt-HR, WH) The unit for measur-
ing electrical energy which equals Watts x
Hours.
Ground The reference potential of a circuit. In
automotive use, the result of attaching one
battery cable to the body or frame which is used
as a path for completing a circuit in lieu of a
direct wire from a component. This method is
not suitable for connecting the negative cable
of the inverter to ground. Instead, route the
cable directly to the negative terminal of the
battery.
Wet Cell Battery A type of battery that uses
liquid as an electrolyte. The wet cell battery
requires periodic maintenance; cleaning the
connections, checking the electrolyte level and
performing an equalization cycle.
LED (Light Emitting Diode) Indicator light.
Negative Designating or pertaining to electrical
potential. The negative terminal is the point
from which electrons flow during discharge.
Ohm A unit for measuring electrical resistance.
Ohm's Law Expresses the relationship be-
tween Voltage (V), Current (I) in an electrical
circuit with resistance (R). It can be expressed
as follows: V=IR. If any two of the three
values are known, the third value can be calcu-
lated by using the above formula.
Positive Designating or pertaining to electrical
potential; opposite of negative. The positive
battery terminal is the point where electrons
return to the battery during discharge.
