IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
Before using your PI-140, read and understand this Owner’s
Manual.
• Keep the inverter well ventilated in order to properly dis-
perse heat generated while it is in use. Make sure there
are several inches of clearance around the top and sides
and do not block the slots of the inverter.
• Make sure the inverter is not close to any potential source
of inammable fumes, gases or clothing.
• Keep the inverter dry.
• DO NOT allow it to come into contact with rain or 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 source are wet. Water and many
other liquids can conduct electricity, which may lead to
serious injury.
• Do not place the inverter on or near heating vents, radia-
tors or other sources of heat.
• Do not place the inverter in direct sunlight. The ideal air
temperature for operation is between 50° and 80°F.
• Do not use near open engine compartment.
• Only connect the power inverter to a 12-volt battery acces-
sory outlet. Make sure the AC plug connection is tight.
• Do not modify the AC receptacle in any way.
• Use only 15-amp fuses.

BEFORE USING PI-140 POWER INVERTER
It is important to know the continuous wattage of the device
you plan to use with the inverter. The PI-140 must be used
with devices drawing 140 watts or less. If the wattage is not
marked on the device, an estimate can be made by multiply-
ing the AC input current (Amps) by the AC voltage (110V).
Devices like TVs, fans or electric motors require additional
power to start (commonly known as the “starting or peak
power”). The PI-140 can supply a momentary surge in watt-
age; however even devices rated less than the maximum 140
watts can exceed the inverters surge capability and cause
an automatic overload shutdown.
Make sure the device you are using is compatible with a
modied sine wave inverter.
OPERATING INSTRUCTIONS
1. Push the PI-140 rmly into the 12V accessory outlet. The
LED indicator light should glow GREEN verifying the
inverter is receiving power. (If connecting in a vehicle,
remove the cigarette lighter from its outlet.)
2. Make sure that the device to be operated is turned
OFF.
3. Plug the device into the PI-140 AC outlet.
4. Turn the device on. If the LED Indicator briey blinks

4
when you rst plug the inverter in, it is a sign that there
is a short circuit within the power supply. Remove the
12-volt plug from the 12-volt accessory outlet. Firmly
reinsert the plug. If this does not remedy the problem,
try using a different 12-volt accessory power outlet.
NOTE: A ‘’buzzing’’ sound emitted from inexpensive
sound systems is the result of ineffective lters in the
sound system. This can be resolved by purchasing a
sound system with a higher quality power supply or
higher quality lter.
POWER SOURCE
Your average automobile or marine battery at full charge
will provide an ample power supply to the inverter for ap-
proximately 3 hours when the engine is off. The actual length
of time the inverter will function depends on the age and
condition of the battery and the power demand being placed
by the device being operated with the inverter.
Turn OFF the device plugged into the inverter before starting
the engine. To maintain battery power, run the engine every
2 to 3 hours for approximately 10 minutes to recharge the
battery. While the PI-140 draws very low amperage when not
in use, it should be unplugged to avoid battery drain.

USAGE EXAMPLES
Device Type Estimate Wattage
Cell Phones, MP 3 Players 10 watts
Portable CD 50 watts
Laptop Computers 90 watts
Video Games 100 watts
LED INDICATOR AND OVERLOAD PROTECTION
The LED glows GREEN automatically when plugged into
a 12V DC source and will not glow under the following
conditions:
1. When the power input from the vehicle’s battery drops
to approximately 10 volts, low battery shutdown occurs
and inverter shuts off.
2. When the power input the vehicle’s battery exceeds
15 volts, high voltage overload protections occurs.
3. The continuous load demand from the equipment or
device being operated exceeds 140 watts.
4. The case temperature becomes hot (exceeds 145°F).
Reset:
To reset after shutdown occurs, check the source of the
problem and correct. Reinsert the inverter into the 12V ac-
cessory outlet.

TROUBLESHOOTING
PROBLEM: Low or No Output Voltage
Reason/Solution
1. Poor contact at terminals.
Unplug and reinsert PI-140.
2. Equipment being operated is drawing too much
power.
Use a higher capacity inverter or do not use the
device.
3. Inverter is too hot (thermal shut down).
Allow inverter to cool. Check for adequate ventila-
tion. Reduced the load on the inverter to rated
continuous power output.
4. Fuse blows.
A blown fuse is usually caused by reverse polarity
or a short circuit within the device being operated.
To replace:
• Disconnect the device immediately.
• Find the source of the problem, and repair it.
• Install a new 15-amp fuse. Do not tighten the fuse
cap too far; nger tight is sufcient.
NOTE: Installing a fuse higher than 15-amps may
cause damage to the inverter.
5. Inverter may be defective.
