Unpacking
When unpacking, check to make sure the following parts are included. If any parts
are missing or broken, please call Harbor Freight Tools at the number on the cover
of this manual as soon as possible.
Operation
For the power inverter to work properly, your power source must provide between
10 to 15 volts DC, and the power source must provide enough current (i.e., 33
amps to operate the load of 400 Watts or under).
Caution: This inverter must only be connected to batteries with a nominal out-
put voltage of 12 volts. Lower voltage will not operate the inverter properly,
and more voltage could damage it. Do not use this inverter with positive ground
electrical systems.
1. Place the Power Inverter on a flat surface. Make sure it
has adequate ventilation and is not in direct sunlight.
2. Connect either the lighter output connector cable or the
battery clamp cable lugs to the red and black terminal
screws on the back of the inverter. Securely tighten.
3. The Power Inverter can be used either while the engine is
running or off. Insert the Lighter Output Connector Cable
plug firmly into the cigarette lighter socket. Or, connect the Battery Cable
Clamps to the negative (black) and Positive (red) terminals of the battery.
4. Plug the 110 VAC device(s) you wish to power into the 3-prong AC
Receptacles. See photo on the next page. The appliance(s) must not use
more than 400 (total) watts during continuous operation.
