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. 

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.

CAUTION Reverse polarity connections (positive 
to negative) will blow internal fuses in the inverter
and may permanently damage the unit. Such
damage is not covered by the warranty.

CAUTION Remove any jewelry (watch, ring, etc.).
Be careful not to short circuit the battery with any
metallic object (wrench, etc.).

WARNING You may observe a spark when making
the connection because current can flow to charge
the capacitors in the inverter. Do not make this
connection in the presence of flammable fumes.
Explosion or fire may result. Thoroughly ventilate
the battery compartment before making this
connection.
