3. Connect cable to your vehicle’s cigarette lighter socket.

NOTE 

If the inverter is to be used at levels above 150 watts for 

extended periods of time, a direct connection to the battery is 
recommended. Do not use the cigarette cord for loads higher 
than 150 watts. Please contact your local dealer or customer 
assistance for the proper cord for direct to battery connections.

Connecting Cables

Power wire and wiring are very important to the performance of the inverter. 
Because the inverter has a low voltage, high current input, low resistance wiring 
is essential between the battery and inverter. This is so it can deliver the maximum
amount of energy to the load. 

Only use the cables provided with your power inverter.

To Connect the Cables Between the Inverter and the Battery:

1. Turn the 

On/Off Switch

on the inverter to the Off position. If the power 

source is a DC power supply, switch it Off as well.

2. Connect cable to the 

Power Input Terminals

on right side panel of the 

inverter. The red terminal is positive (+) and the black terminal is 
negative (-). Insert the ends of the cables onto the terminals and 
tighten the screws to clamp the cables safely.
