WHISTLER inverters convert low voltage, direct current  
(DC) to 110 volt alternating household current (AC). The  
AC output is called “modified sine wave”. See “Technical  
Operating Principles” section for more information.  
Depending on the model and its rated capacity,  
WHISTLER inverters draw power either from standard 12  
volt automobile and marine batteries or from portable  
high power 12 volt sources.

IMPORTANT INFORMATION  
INVERTER BASICS  
Important Information About Your New WHISTLER  
Inverter.  
Getting Started  
Power equipment and appliances which operate with motors  
or tubes require an initial surge of power to get them up and  
running. This power surge is referred to as the "starting load"  
or "peak load." (By comparison, electrical devices such as  
standard light bulbs do not require a large starting load).  
Once the equipment or appliance has been powered up, it  
settles down to a slower pace and requires far less electrical  
power to operate. This lower power requirement is referred  
to as the "continuous load."  
This manual will provide you with directions for the safe  
and efficient operation of your WHISTLER inverter. Read  
the manual carefully before using your new WHISTLER  
inverter and keep the manual on file for future reference.  
Notes:  
In order to ensure that the capacity of your WHISTLER  
inverter is sufficient to meet the required start up load, you  
must first determine the power consumption of the equip-  
ment or appliance you plan to operate.  
Your WHISTLER inverter is designed to operate from a 12  
volt power source only. Never attempt to connect your  
Whistler inverter to any other power source, including any  
AC power source.  
Power consumption is rated either in wattage or in amperes,  
and information regarding the required "watts" or "amps"  
generally is stamped or printed on most appliances and  
equipment. If this information is not indicated on the  
appliance or equipment, check the owners manual. Contact  
the appliance or equipment manufacturer to determine  
if the device you are using (TV’s, battery re-charger,  
computer, medical equipment, etc.) is compatible with a  
modified sine wave.  
The length of the supplied cables is matched for the  
current needed by the inverter. Making this cable longer  
will make the inverter less efficient and may cause the  
cables to heat up.  
Do not attempt to lengthen the supplied power cables.  
110 volts can be lethal. Improper use of your WHISTLER  
inverter may result in property damage, personal injury or  
loss of life.  
Not recommended for use with medical equipment.  
Check with the appliance manufacturer for compatibility  
with modified sine wave inverters. Some appliances may  
not work well, not at all or be damaged. For more informa-  
tion on compatibility issues, please visit our inverter FAQ  
If the power consumption is rated in amps, multiply the  
number of amps by 110 (AC voltage) to determine the  
comparable wattage rating. Induction motors, as well as  
some televisions, may require 2 to 6 times their wattage  
rating for startup.  
For further information on the fundamental operating  
principles of WHISTLER inverters and related technical  
data, see "Technical Operating Principles."

INVERTER BASICS  
INVERTER BASICS  
Don’t Push It.  
If a piece of equipment or an appliance will not operate, first  
confirm that the inverter has been properly connected to  
the 12 volt power source (See "Making The Connection"). If  
all connections have been properly made, turn the inverter  
rocker switch ON (l), OFF (O) and ON (l) again in quick suc-  
cession. If this procedure is unsuccessful, it is likely that the  
inverter does not have the required start up capacity to  
operate the equipment or appliance in question.  
Although your WHISTLER inverter has the capacity to pro-  
vide power output (excess current) equal to approximately  
two times its rated wattage capacity for a very brief period,  
it is designed to operate equipment and appliances with  
start up load wattage ratings no higher than its own maxi-  
mum continuous wattage rating.  
For example, the 400 watt model has a maximum continu-  
ous rating of 400 watts. Although this model has the capac-  
ity to briefly provide higher watts of power (that is, excess  
current), it is designed to operate equipment and appli-  
ances with start up load requirements of 400 watts or less.  
Note:  
Most heat generating appliances require start up loads  
in excess of 1000 watts and this inverter will not operate  
such appliances as coffee makers, irons, hair dryers or  
heaters.  
Consequently, if the start up load rating of your equipment  
or appliance is the same or approximately the same as the  
maximum continuous rating of the inverter, the inverter will  
attempt to start loads above the continuous rating for up to  
10 seconds.  
The inverter is designed to shut down automatically in the  
event of a power overload. Testing appliances and equip-  
ment with start up load ratings comparable to your inverter  
wattage rating will not damage it. However, make sure the  
appliance you are testing is compatible with modified sine  
wave inverters. See page 4 for more information.

OPERATION  
OPERATION  
6. Remove the cigarette lighter and push the adapter plug  
firmly into the cigarette lighter socket.* (Make certain  
both the socket and adapter plugs are clean.)  
Making the Connection.  
This inverter is designed to connect to your 12 volt battery  
using the light socket plug or by the supplied battery cables  
(for appliances over 150 watts* 400 watt model).  
Making The Connection.  
1. Make certain that the inverter rocker switch is in the  
OFF (O) position.  
Note:  
If the equipment or appliance you intend to operate  
requires more than 150 watts of continuous power, this  
inverter should be connected directly to the power  
source using the Hard Wire Cables (400 watt model) or  
the optional Hard Wire Adapter P/N PP010DC. Failure to  
do so may result in serious damage to the power cord or  
to the cigarette socket lighter wiring.  
Loose connections can result in a severe decrease in volt-  
age which may cause damage to the wires and insulation.  
Failure to make proper connection between the inverter  
and the power source will result in reverse polarity.  
Reverse polarity will blow the internal fuses in the invert-  
er and may cause permanent damage to the inverter.  
Damage caused by reverse polarity is not covered under  
the WHISTLER warranty.  
2. Connect the lighter plug or hardwire cables to the  
power input terminals at the rear of the inverter and  
tighten the screws to make a secure connection.  
Do not use tools to tighten these screws.  
Steps 3 - 5 are used when and appliance requires  
over 150 watts.* Step 6 is for appliances under  
150 watts.*  
3. Connect the cable from the (BLACK) Negative (-) ter-  
minal on the inverter to the Negative (-) terminal on  
the 12 volt power source. Make certain the connec-  
tion is secure.  
4. Confirm that the cable you have just installed is prop-  
erly connected. Specifically, make certain that the  
cable is connected to the Negative (-) terminals on  
both the inverter and the 12 volt power source.  
5. Connect the cable from the (RED) Positive (+) terminal  
on the inverter to the Positive (+) terminal on the  
power source.  
Making the connection between the Positive terminals  
may cause a spark as a result of current flowing to the  
capacitors in the inverter. This is a normal occurrence.  
Due to the potential for sparking, however, it is extreme-  
ly important that both the inverter and the 12 volt battery  
be well removed from any possible source of flammable  
fumes or gases.  
Failure to heed this warning could result in fire or explo-  
sion.  
RED (+)  
*Some vehicle lighter sockets may only supply 10 amps or approximately 100 watts. If so,  
use the hardwire cables. Check vehicles owners manual for lighter socket fuse rating.

OPERATION  
OPERATION  
The use of an extension cord from the inverter to the appli-  
ance or equipment being operated will not significantly  
decrease the power being generated by the inverter. For  
best operating results, the extension cord should be no  
more than 50 feet long.  
Check frequently to ensure that the input and output con-  
nections are secure. Loose connections may damage the  
inverter or the power source or may generate excessive  
heat.  
400 watt model - If the supplied cables are too short  
to allow for placement of the inverter in a desired  
location, the inverter may be connected to the power  
source using a #8 wire, up to 12’ - #4 wire for longer  
lengths. The steps outlined for making the connec-  
tion and the related safety precautions remain  
unchanged.  
7. Turn the inverter rocker switch to the ON (I) position.  
The LED Indicator Light should glow GREEN confirm-  
ing that there is power running to the inverter.  
8. Turn the inverter rocker switch to the OFF (O) position.  
(The GREEN LED Power Indicator light may “blink”  
briefly and/or the internal audible alarm may make a  
momentary “chirp”. This is normal).  
9. Confirm that the equipment or appliance to be oper-  
ated is turned off. Plug the equipment or appliance  
into one of the three AC receptacles on the front  
panel of the the inverter.  
Important Information on Battery Chargers  
Using your inverter to recharge units designed to charge such  
portable equipment as power tools, flashlights, video cameras and  
laptop computers may cause damage to the inverter or the  
charging unit. Check with the appliance manufacturer for com-  
patibility with sine wave inverters if you’re unsure.  
Although we advise against it, if you attempt to recharge a charg-  
ing unit, monitor the temperature of the charging unit for approx-  
imately 10 minutes. If the charging unit becomes unusually warm,  
disconnect it from the inverter immediately.  
10. Turn the inverter to the ON (I) position. Turn on the  
equipment or appliance.  
Note:  
As indicated in Step 7 above, the audible alarm may  
make a momentary “chirp” when the inverter is  
turned OFF (O). The same alarm may also sound  
when the inverter is being connected to or discon-  
nected from the 12 volt power source. Again, this is  
normal.  
Don’t Blow A Fuse.  
This inverter is equipped with an internal spade type fuse(s). With  
reasonable care, it should not be necessary to replace the fuse(s)  
in your inverter. We have included an “open fuse” monitor on the  
DC panel.  
Most blown fuses are the result of reverse polarity or a short circuit

ADDITIONAL FEATURES  
OPERATION  
within the appliance or equipment being operated. If the  
fuse(s) does blow, turn off and disconnect the appliance or  
equipment from the inverter immediately, repair the related  
problem and replace the fuse(s). The internal fuses are  
replaceable, however, only electronically knowledgeable  
people should attempt fuse replacement  
Automatic Shut Down & Related Safety Features.  
Each inverter has an unique LED indicator warning light sys-  
tem which operates in conjunction with the automatic shut  
down feature. These indicator lights operate as follows:  
GREEN LED:  
RED LED:  
System ready.  
Note:  
Make certain to correct the source of the overload  
which caused the blown fuse before turning your  
inverter back ON (l).  
System overload/automatic shut down.  
Your inverter will shut down automatically when any of the  
following problems occur:  
The Power Source.  
1. The power input from the battery drops below  
10 volts.  
When the engine is off, most batteries will provide an ample  
power supply to the inverter for one to two hours. The actual  
length of time is a function of several variables including the  
age and condition of the battery and the power demand  
being placed on it by the equipment being operated with the  
inverter.  
2. The power input from the battery exceeds 15 volts.  
3. The continuous draw of the appliance or equipment  
being operated exceeds the design parameters of the  
inverter.  
The inverters are also equipped with the following additional  
safety features:  
If you are using the inverter while the engine is off, we  
recommend you start the engine every hour and let it run for  
at least 10 minutes to recharge the battery. We also recom-  
mend that the device plugged into the inverter be turned off  
before turning over the engine.  
1. Thermal Cut Off:  
Automatic shut down if internal temperature exceeds safe  
design parameters.  
Although it is not necessary to disconnect the inverter when  
turning over the engine, the inverter may momentarily cease  
operation as the battery voltage decreases. When the invert-  
er is not supplying power, and turned on, it draws very low  
amperage from the battery (<0.40 A ).

CARE AND MAINTENANCE  
ADDITIONAL FEATURES  
To maintain your inverter in proper working condition, note  
the following important safety precautions:  
2. Low Battery Voltage Alarm/Shutdown Protection  
a) When the input voltage from the 12 volt power source  
drops below 10.5 volts, an audible tone will be heard.  
This is the low battery voltage alarm.  
MOISTURE. Keep the inverter dry. Do not expose it  
to moisture. Do not operate the inverter if you, the  
inverter, the device being operated or any other sur-  
faces that may come in contact with any power  
sources are wet. Water and many other liquids can  
conduct electricity which may lead to serious injury or  
death.  
b) The inverter will automatically shut down when the  
input voltage drops below 10 volts. This protects the  
battery from completely draining.  
In the event of automatic shut down or continuous audible  
alarm, turn the inverter rocker switch to the OFF (O) position  
until the source of the related problem has been identified  
and resolved.  
HEAT. For peak efficiency, the ambient air tempera-  
ture should be between 50° and 80° F. Avoid placing  
the inverter on or near heating vents, radiators or  
other sources of heat. Do not place the inverter in  
direct sunlight.  
Some Powerful Advice.  
Your WHISTLER inverter will work best when placed on a rea-  
sonably flat surface. The floor or seat of your car or truck both  
are good locations.  
VENTILATION. In order to disperse the heat generat-  
ed while the inverter is in operation, keep it well venti-  
lated. While in use, maintain several inches of clear-  
ance around the top and sides of the inverter.  
When driving with the inverter in operation, make certain that  
neither the inverter nor the power cords will impede safe  
operation of your vehicle. Keep the unit and all cords clear of  
the steering wheel, gas, brake and clutch pedals and gear  
shift.  
FUMES & GASES. Avoid using the inverter near  
flammable materials. Do not place the inverter in  
areas such as battery compartments. Where fumes or  
gases may accumulate.  
In Review.  
Never attempt to operate your WHISTLER inverter  
from any power source other than a 12 volt battery or  
group of batteries that total 12 volts.

OPERATING PRINCIPLES  
OPERATING PRINCIPLES  
For You Technical Types.  
majority of AC voltmeters are calibrated for RMS voltage  
and assume that the measured waveform will be a pure sine  
wave.  
1. Basic Operating Principles:  
WHISTLER inverters work in two stages. During the first  
stage, the DC to DC converter increases the DC input voltage  
from the power source (e.g. a 12 volt battery) to 145 volts DC.  
In the second stage, the high voltage DC is converted to 110  
volts (60 Hz AC) using advanced power MOSFET transistors  
in a full bridge configuration. The result is excellent overload  
capability and the capacity to operate difficult reactive loads.  
The output waveform resulting from these conversions is a  
"quasi-sine wave" or a "modified sine wave" as shown on the  
following page.  
Consequently, these meters will not read the RMS modified  
sine wave voltage correctly and, when measuring your  
WHISTLER inverter output, the meters will read about 20 to  
30 volts too low. To accurately measure the output volt-  
age of your inverter, use a true RMS reading voltmeter  
such as a Fluke 87, Fluke 8060A, Beckman 4410, Triplett 4200  
or any multimeter identified as "True RMS."  
For more information on inverters see our Inverter FAQ

utilities and has a broad range of applications.
