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  
modified sine wave inverter.  
OPERATINg INSTRUCTIONS  
1. Push the PI-140 firmly 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.  
ꢀ. Plug the device into the PI-140 AC outlet.  
4. Turn the device on. If the LED Indicator briefly blinks  
when you first 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 filters in the  
sound system. This can be resolved by purchasing a  
sound system with a higher quality power supply or  
higher quality filter.  
POWER SOURCE  
Your average automobile or marine battery at full charge  
will provide an ample power supply to the inverter for ap-  
proximately ꢀ 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 ꢀ 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.

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.  
ꢀ. 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.  
ꢀ. 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; finger tight is sufficient.  
NOTE: Installing a fuse higher than 15-amps may  
cause damage to the inverter.  
5. Inverter may be defective.
