Connecting Inverter Cables
The inverter and the power source must be in the oFF
mode.
Inverter Connection:
1. locate the positive and negative plastic terminals
located on the left side of the inverter. Using a flathead
or standard screwdriver, unscrew the positive (red) and
negative (black) terminal screws just enough to be able
to insert the bare end of the connector cables.
2. Insert the bare end of the positive (red) cable into the
positive terminal and bare end of the negative (black)
cable into the negative terminal. Tighten each terminal
screw so the cable cannot come loose.
Connecting Inverter Cables to 12V Battery or 12V
Power Source
1. Keep hands, hair, clothing and jewelry clear of battery
terminals.
2. Wear protective eye and clothing protection.
3. Connect the negative (black) inverter terminal cable to
the power source negative battery terminal. Connect
the positive (red) inverter terminal cable to the power
source positive terminal. Make sure the connections are
secure.
Note: Failure to make the correct connections will result in
blown fuses and permanent damage to the inverter.
