INTRODUCTION
Keep this manual and the System Installation Guide in the folder mounted inside the
unit.
This unit is a microprocessor controlled PWM (Pulse Width Modulated) pure sine wave
based DC to AC power inverter utilizing MOSFET technology. It integrates a fully automatic
3-rate battery charger, a solid-state transfer system, control circuitry, self testing and
recording digital meter display, and maintenance free sealed lead calcium type batteries.
The system components are carefully matched to make the unit a completely self-contained,
fully automatic standby power source for operation on all types of lighting loads. The
batteries are sized and tested per UL-924 and Life Safety Code ANSI / NFPA 101, providing
emergency power for a minimum of 90 minutes.
If the duration of a power failure is greater than the batteries storage capability, the inverter
will automatically shut down when the battery voltage reaches 85% of the nominal DC
voltage. This feature protects the battery from being permanently damaged from a deep
discharge that could cause cell reversal. This battery protection feature is called "Low
Voltage Disconnect" or L.V.D.
When the AC power is restored after a full discharge, the system will be ready for another
power failure within 24hrs. If another power failure occurs before the 24-hour recharge time,
the run time will be decreased.
The front panel display incorporates an alphanumeric 2x20 LCD character display, LED
status indicators and a 4 x 4 keypad. All user interface functions are available from the front
panel assembly.
Utilizing a small footprint, this unit is for use with any lighting load including quartz, HID,
incandescent, fluorescent and halogen.

Environment
Make sure the environment is a clean, cool, dry place with normal ventilation.
Storage Temperature
Store the batteries (in the system or battery cabinet) at -18 to 40°C (0 to 104°F). Batteries
have a longer shelf life if they are stored below 25°C (77°F). Keep stored batteries fully
charged. Recharge the batteries every 90–120 days. The system or battery cabinet without
batteries may be stored at -20 to 70°C (-4 to 158°F).
Ventilation
The air around the unit must be clean, dust-free, and free of corrosive chemicals or other
contaminants. Do not place the system or batteries in a sealed room or container.
Operating Temperature
System can operate from 20° to 30°C (68° to 86°F) and up to 95% relative humidity. The
batteries’ service life is longer if the operating temperature stays below 25°C (77°F).
Batteries
The temperature should be near 25°C (77°F) for optimum battery performance. Batteries are
less efficient at temperatures below 18°C (65°F), and high temperatures reduce battery life.
Typically, at about 35°C (95°F), battery life is half of what it would be at a normal
temperature of 25°C (77°F). At about 45°C (113°F), battery life is one-fourth of normal.
Make sure that heaters, sunlight, air conditioners, or outside air vents are not directed
toward the batteries. These conditions can make the temperature within battery strings vary,
which can cause differences in the batteries’ voltages. Eventually, these conditions affect
battery performance.
If the batteries are not in the system, remember that the batteries should be installed as
close as possible to the unit to reduce DC wiring costs and improve battery performance.
Do not allow tobacco smoking, sparks, or flames in the system location because hydrogen is
concentrated under the vent cap of each cell of the battery. Hydrogen is highly explosive,
and it is hard to detect because it is colorless, odorless, and lighter than air.
Every type of battery can produce hydrogen gas, even sealed maintenance-free batteries.
The gas is vented through the vent caps and into the air, mainly when the unit is charging
the batteries. The batteries produce the most hydrogen when maximum voltage is present in
fully charged batteries; the batteries do not produce hydrogen during float charging. The
amount of current that the charger supplies to the batteries (not the battery ampere-hour)
determines how much hydrogen is produced.
High Altitude Operation
The maximum operating ambient temperature drops 1°C per 300m (2°F per 1000 ft) above
sea level. Maximum elevation is 3000m (10,000 ft).

OPERATION
The following is a description of the status LED's located on the front panel and the internal fan.
AC Present
When the AC Mains is present, the LED will illuminate. If a power failure was long in duration, or the
AC mains was disconnected by some other means (Circuit breaker open) the AC Present LED would
not be illuminated. When the control circuit senses that the line has dropped below an acceptable
level (Black Out, Brown Out, or Transient), the inverter will energize for at least one minute. So, if the
power failure was a momentary glitch, the AC present LED would be illuminated but the inverter
would be running.
System Ready
When the system has adequate battery voltage to transfer, the System Ready LED will illuminate.
This feature prevents damage from multiple deep discharges of the battery.
Battery Charging
When the AC Mains is connected to the line and the battery is charging under normal conditions, the
Battery Charging LED will illuminate.
Battery Power
When the inverter is producing output power (battery is being discharged), the Battery Power LED will
be illuminated.
Fault
This is a summary Fault indication. When there is a fault condition present, the Fault LED will
illuminate. To view which fault is present, use the keypad and LCD display feature.
The front panel display will provide the user with a variety of information. It has a full compliment of
Meter functions, Control functions and Program functions.
Fan
The fan operates during emergency mode and only during normal mode when the batteries are being
charged. When the batteries reach float condition (trickle charge) the fan turns off.

MAINTENANCE AND SERVICE
The Self-testing feature of the inverter ensures that the system is tested at least once per
month for 5 minutes and once per year for 90 minutes. If there are any problems with the
self-tests, the fault log shall indicate which faults occurred. Please see the fault descriptions
and troubleshooting guide.
A few simple maintenance operations performed periodically will help ensure many years of
trouble free operation. Battery terminals should be checked for tightness and corrosion. If
severe corrosion is evident, maintenance is required to correct this situation.
Since the unit depends on unrestricted airflow for cooling of power handling components, it
is important to keep the air vents free of any obstruction. If the environment tends to be
extremely dusty, occasionally blow away any accumulation of dust on components. Please
follow the shutdown procedure before cleaning.
CAUTION: Follow the shutdown procedure (See Chapter 3) before cleaning. An authorized
technician only should perform Service!
