IMPORTANT SAFETY INSTRUCTIONS
Save These Instructions
Before using your PID-750, 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ammablefumes,gasesorclothing.
• Keeptheinverterdry.
•DONOTallowtheinverter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theinverternearanopenenginecompart-
ment.

• OnlyconnectthePower Inverter to a 12-Volt battery. Make
sure the AC plug connection is tight.
• DonotmodifytheACreceptacleinanyway.
• Useonly45-ampfuses.
• This device does not include an internal Ground Fault
Circuit Interrupter (GFCI). For GFCI protection, use a
ColemanCable02822GFCIoutlet.
WARNING: Handling the cord on this product or cords as-
sociated with accessories sold with this product, may expose
you to lead, a chemical known to the State of California to
cause cancer and birth defects or other reproductive harm.
Wash hands after handling.
BEFORE USING PID-750 POWER INVERTER
It is important to know the continuous wattage of the
device you plan to use with the inverter. The PID-750 must
be used with devices drawing 750 watts or less. If the
wattage is not marked on the device, an estimate can be
madebymultiplying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 PID-750 can supply a momentary surge
in wattage; however even devices rated less than the
maximum 750 watts can exceed the inverters surge capa-
bility and cause an automatic overload shutdown.

Make sure the device you are using is compatible with a
modiedsinewaveinverter.
OPERATING INSTRUCTIONS
Connecting to a 12 Volt Battery:
The PID-750 battery clamps allow quick hook-up to a
12Vbattery.MakesurethePID-750andthedevice(s)are
turned OFF.
1. Unscrewthepositive(red)andnegative(black)plastic
connector knobs from the back of the inverter.
2. Slip the end of the red (positive) battery cable clamp
wireoverthered(positive)threadedextensionandthen
screw on the connector knob and tighten so the wire is
firmly attached. Repeat the same process for the black
wire.
3. Connectthered(positive)batterycabletothepositive
(+)batteryterminaltakingcaretoshieldeyes,clothing
and hands from battery acid. Connect the black battery
clamptonegative(-)groundonthebattery.
4. Plug the device into the Power Inverter 750 AC outlet.
NOTE: If using more than one device, the total combined
wattage of both devices must not exceed 750 watts.
5. ToturntheinverterON(I)orOFF(0),pressandhold
buttonfor2seconds.TurntheinverterON.

5
6. TurnthedeviceON.
7. To disconnect the PID-750, reverse the above steps.
NOTE: If there is a short circuit or power surge in the
device, the alarm will sound. To turn off the alarm, press
thebutton.CycleinverterpowerOFFandON.Ifproblem
persists, use a larger inverter or a smaller device.
POWER SOURCE
Your average automobile or marine battery at full charge
will provide an ample power supply to the inverter for
approximately 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 and 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 PID-750
draws very low amperage when not in use, it should be
unplugged to avoid battery drain.

LED DISPLAY
The LED readouts identify the current status of the
PID-750.
VOLTAGE IN: Voltage of vehicle’s battery or Portable
Power jump starter/DC power source.
VOLTAGE OUT: Voltage supplied to device through AC
receptacle.
POWER OUT: Power or wattage supplied to device
plugged into the inverter.
An audio alarm will sound when the following codes display.
Tostopthealarm,presstheON/OFFLEDSelectorbutton:
BaD – Inverter is not functional. See warranty and call
Customer Service 800-621-5485 (Hours: 7 a.m. – 4:30
p.m.CST).
Hi b – Vehicle’s battery voltage is more than 15.5 volts.
Inverter will automatically restart after the voltage drops
below 15.0 volts.
Hi P – The continuous load demand from the device
exceeds 750 watts.
HoT – Inverter is overheated and automatically turns off
for a period of 1–3 minutes to cool. Make sure inverter is
well ventilated. It will automatically restart after it cools.
Lo b – Vehicle’s battery voltage is less than 10.5 volts.

mands too much surge power.
 CycleinverterpowerOFFandON.
If problem persists, use a larger inverter or a
smaller device.
Remove defective device.
See warranty and call Customer Service
800-621-5485(Hours:7a.m.–4:30p.m.CST).

Recharge/replace low battery.
3. Display shows Voltage In between 10.5 and 11.0
Volts.
12 Volt battery is low.
Recharge/replace low battery.
Inverter will automatically shut off after battery volt-
age reaches 10.5 volts.
4. Display shows Hi b . 12 Volt voltage is too high.
If in a vehicle, repair/replace the alternator or
charging system.
Use a properly sized and rated 12 Volt battery.
If input voltage returns to 15 volts or less, the in-
verter will automatically restart.

5. Display shows Hi P. Device demands more than 750
Watts continuous power.
 CycleinverterpowerOFFandON.
If problem persists, use a larger inverter or a
smaller device.
6. Display shows HoT. Inverter is too hot.
Increase ventilation to inverter.
Move inverter to a cooler area.
Reduce the power consumption of the device.
Inverter will automatically reset after cooling.
PROBLEM: Inverter Does Not Turn On
Reason/Solution
1. Poor contact at terminals.
Unplug and reinsert PID-750.
2. Fuse is blown.
A blown fuse is usually caused by reverse polar-
ity or a short circuit within the inverter. To replace,
contactaqualiedservicetechnicianwhowill
diagnose the inverter and replace the fuse with the
appropriate replacement.
3. Inverter may be defective.
