AWord About WHISTLER Inverters.
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.

INVERTER BASICS
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."
In order to ensurethat the capacity of your Whistler inverter
is sufficient to meet the required start up load, you must first
determine the power consumption of the equipment or
appliance you plan to operate.
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 owner’s manual. Contact
the appliance or equipment manufacturer to determine
if the device you are using (TV’s, battery re-charger,
computer, etc.) is compatible with a modified sine wave.
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
to startup.
For further information on the fundamental operating
principles of Whistler inverters and related technical data,
see "Technical Operating Principles."

IMPORTANT INFORMATION
Important Information About Your New Whistler Inverter.
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:
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.
• 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 information on compatibility issues,
please visit our inverter FAQ page at
www.whistlergroup.com.

INVERTER BASICS
Don’t Push It.
Although your Whistler inverter has the capacity to provide
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 maximum
continuous wattage rating.
For example, the 800 model has a maximum continuous
rating of 800 watts. Although this model has the capacity to
briefly provide higher watts of power (that is, excess
current), it is designed to operate equipment and
appliances with start up load requirements of 800 watts or
less.
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.
Todetermine whether your inverter will operate a particular
piece of equipment or appliance, run a test. The inverter is
designed to shut down automatically in the event of a
power overload. Testing appliances and equipment with
start up load ratings comparable to your inverter wattage
rating will not damage it.
9
INVERTER BASICS
8
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
succession. 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.
Note:
• Most heat generating appliances require start up
loads in excess of 1000 watts and the inverter will not
operate such appliances as coffee makers, irons, hair
dryers or heaters.

OPERATION
Making the Connection.
This inverter is designed to connect to your 12 volt battery
by the supplied #8 gauge cables.
1. Make certain that the inverter’s rocker switch is in the
OFF (O) position.
2. Connect the cables to the power input terminals at
the rear of the inverter and tighten the screws to make
asecure connection. Do not use tools to tighten
these screws.
3. Connect the cable from the (BLACK) Negative (-)
terminal on the inverter to the Negative (-) terminal on
the 12 volt power source. Make certain the
connection is secure.
4. Confirm that the cable you have just installed is
properly 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.
11
OPERATION
10
Note:
• Loose connections can result in a severe decrease in
voltage 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 inverter and may cause permanent damage to the
inverter. Damage caused by reverse polarity is not
covered under the Whistler warranty.
• 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 extremely important that both the
inverter and the 12 volt battery be well removed from
any possible source of flammable fumes or gases.
Failureto heed this warning could result in fireor
explosion.
6. For safe and proper operation of the inverter when
not using the supplied cables, connect the inverter to
the power source with the thickest wire available and
in the shortest length practical. When the inverter and
the battery are set up within four feet of each other, use a
minimum of #8 gauge wire to make the connections.
Within four to six feet, use #6 gauge wire. At distances
between six feet to ten feet, use #4 gauge wires
connected to the battery. Regardless of the wire gauge
selected to make the connections to the battery, we
recommend use of an “O Ring Adapter.” The adapter is
available through electronic supply stores or high end
car audio installers.

OPERATION
Note:
• 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 disconnected from the 12 volt power source.
Again, this is normal.
• The use of an extension cord from the inverter to the
appliance 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 ensurethat the input and output
connections aresecure. Loose connections may damage
the inverter,the power source, or may generate
excessive heat.
13
OPERATION
7. Run a ground from the Ground Lug Terminal at the
rear of the inverter to a proper grounding point using
the shortest practical length of 18 AWG wire.
Selection of the grounding point will depend on
where you are using the inverter. The ground wire may
be connected to the chassis of your vehicle or to the
grounding system in your boat or to the earth* if you
areoperating the inverter in a remote location. Before
connecting to the ground, make certain that the
inverter is turned off.
Operating the inverter without properly grounding it
may result in electric shock.
*This ground can’t be the same ground as the AC
ground.
8. Confirmthat the equipment or appliance to be operated
is turned off. Plug the equipment or appliance into one of
the AC receptacles on the front panel of the inverter.
9. Turn the inverter to the ON (I) position. Turn on the
equipment or appliance.
12

The Power Source.
When the engine is off, most batteries will provide 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.
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
recommend that the device plugged into the inverter be
turned off before turning over the engine.
Although it is not necessaryto disconnect the inverter
when turning over the engine, the inverter may
momentarily cease operation as the batteryvoltage
decreases. When the inverter is not supplying power, and
turned on, it draws very low (<0.90 A).
OPERATION
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 compatibility with sine wave
inverters if you’re unsure.
Although we advise against it, if you attempt to recharge
acharging unit, monitor the temperature of the charging
unit for approximately 10 minutes. If the charging unit
becomes unusually warm, disconnect it from the inverter
immediately.
Don’tBlow A Fuse.
This inverter is equipped with two 40 amp spade type
fuses. With reasonable care, it should not be necessary to
replace the fuse(s) in your inverter.
Most blown fuses are the result of reverse polarity or a
short circuit 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).
Note:
• Make certain to correct the source of the overload
which caused the blown fuse before turning your
inverter back ON (l).

ADDITIONAL FEATURES
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.
Wall Mounting:
Whistler inverters have provisions for wall mounting;
slotted holes allow for easy wall mounting of the unit.
For You Television Fans and Audiophiles.
Although the inverter is shielded and filtered to minimize
signal interference, some interference with your television
picturemay be unavoidable, especially with weak signals.
However, here are some suggestions that may improve
the reception.
1. First, make certain that the television antenna pro
duces a clear signal under normal operation
conditions (i.e., at home plugged into a standard
110AC wall outlet). Also, ensure that the antenna
cable is properly shielded and of good quality
2. Change the relative positions of the inverter,antenna
cables and television power cord.
3. Isolate the television, its power cord and antenna
cables and television power cord.
4. Coil the television power cord and the input cables
running from the 12 volt power source to the inverter.
5. Attach a “Ferrite Data Line Filter” to the television
power cord. More than one filter may be required.
These filters are available at most electronic supply
stores including Radio Shack. (Radio Shack Part
Number is 273-105).
ADDITIONAL FEATURES
16
Automatic Shut Down & Related Safety Features.
Each Whistler inverter model has an unique LED Indicator
warning light system which operates in conjunction with
the automatic shut down feature.These indicator lights
operate as follows:
GREEN LED: System ready.
RED LED: System overload/automatic shut down.
Your inverter will shut down automatically when any of the
following problems occur:
1. The power input from the battery drops below
10 volts.
2. The power input from the battery exceeds 16 volts.
3. The continuous draw of the appliance or equipment
being operated exceeds the design parameters of the
inverter.
The inverter is equipped with the following additional safety
features:
1. Thermal Cut Off:
Automatic shut down if internal temperature exceeds safe
design parameters.
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 batteryvoltage alarm.
b) The inverter will automatically shut down when the
input voltage drops below 10 volts. This protects the
battery from completely draining.

Note: Inexpensive sound systems may emit a
“buzzing” sound when operated with the inverter.
This is due to inadequate filters in the sound system.
There is no solution to this problem short of purchasing a
sound system with a higher quality power supply.
Some Powerful Advice.
Your Whistler inverter will work best when placed on a
reasonably flat surface. The floor or seat of your car or truck
both aregood locations.
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.
To maintain your inverter in proper working condition, note
the following important safety precautions:
•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 surfaces that
may come in contact with any power sources arewet.
Water and many other liquids can conduct electricity
which may lead to serious injury or death.
• HEAT. For peak efficiency, the ambient air temperature
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. 18
CARE AND MAINTENANCE CARE AND MAINTENANCE
• VENTILATION. In order to disperse the heat generated
while the inverter is in operation, keep it well
ventilated. While in use, maintain several inches of
clearance around the top and sides of the inverter.
• 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.

OPERATING PRINCIPLES OPERATING PRINCIPLES
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 voltage 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
page at www.whistlergroup.com
Atrue sine wave typical of home AC outlet.
For You Technical Types.
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
afull bridge configuration. The result is excellent overload
capability and the capacity to operate difficult reactive loads.
The output waveformresulting from these conversions is a
"quasi-sine wave" or a "modified sine wave" as shown below
This stepped waveformis similar to the power generated by
utilities and has a broad range of applications.
The modified sine wave produced by
your Whistler Inverter
The modified sine wave produced by your Whistler inverter
has a root mean square(RMS) voltage of 110 volts. The
majority of AC voltmeters are calibrated for RMS voltage and
assume that the measured waveform will be a pure sine wave.
