DC Cable Gage
Minimize cable losses by using the thickest wire available, and the shortest practical length. If the
inverter and the battery are positioned within four feet of each other, a minimum of 0 gage (zero
gage) insulated copper wire should be used to make the connections. If the distance is longer than
4 feet, heavier wire will be required.
Because multiple battery cables are used with this inverter, keep cable gages and lengths the
same. This will ensure that cable losses will be evenly distributed. Use the following table as
a guide to the number of cable connections required. Be sure to include any surge wattage in
determining the cable configurations. Remember that terminals also have current carrying limits.

CONNECTING THE INVERTER
General Information
Loose connections will result in a severe voltage drop that can cause damage to the conductors
and insulation and cause sparking.
Reverse polarity connection will blow the fuses in the inverter and can cause permanent damage
to the inverter.
Damage caused by reverse polarity will void the warranty.
Procedure
1 Make sure the cables are the proper gage and have the fuse holders as close to the battery
bank’s Pos (+) terminal.
2. Install the fuses in the Pos (+) cable.
3. Make sure the ON/OFF switch located on the front panel of the inverter is in the OFF (0)
position. Disconnect any remote switch from the connector on the front panel.
4. Locate the Ground Lug Terminal at the rear of the inverter. Connect an insulated 6 gage copper
wire to the terminal. The other end of the ground wire is connected to a “proper” grounding
point. Use the shortest practical length of wire. Connect this wire to the chassis of your vehicle
or to the grounding system in your boat. In a city, the ground wire can connect to a metal cold
water pipe that goes underground. In remote locations, the ground wire can be connected to an
“earth ground”. This can be an attachment to a six foot long copper clad metal rod driven into the
ground. In the unlikely event of a short circuit, operating the inverter without proper grounding can
