The inverter and power source must be in the OFF mode.

 Make sure you connect your inverter to a 12-volt 

power supply only.
Inverter connection:

Locate the positive and negative plastic terminals located on the 

back of the inverter and remove the terminal caps completely.

Install the positive (red) cable ring lug onto the positive (red) 

terminal screw. Install the negative (black) cable ring lug onto 

the negative (black) terminal screw. Tighten each terminal so 

that the cable cannot come loose.

Remove the cigarette lighter from its outlet.

Push the 12-volt power plug firmly into the outlet.

Keep hands, hair, clothing and jewelry clear of battery terminals.

Wear eye protection and clothing protection.

Connect the positive (red) inverter terminal cable to the 

power source positive (+) or battery terminal. Make sure the 

connection is secure.

Connect the negative (black) inverter terminal cable to the 

power source negative (-) or battery terminal. Make sure the 

connection is secure.

To disconnect the inverter, reverse the above steps.

NOTE: The internal speaker may make a brief “beep” when the 

inverter is being connected to or disconnected from the 12-volt 

power source.

Failure to make the correct connections will result in 

blown fuses and permanent damage to the inverter.
