Ground Wiring

There is a screw on the rear panel labeled Chassis
Ground. This is to connect the chassis of the
inverter to ground. The ground terminal in the AC
outlet on the right side panel of the inverter is
connected to the chassis.
The Chassis Ground screw must be connected to
a grounding point, which will vary depending on
where the unit is installed. Use a #8 AWG copper
wire (preferably with green/yellow insulation) to
connect the chassis ground screw to the ground-
ing point.
• In a vehicle, connect the Chassis Ground to the
chassis of the vehicle.
• In a boat, connect to the boat grounding
system.
• In a fixed location, connect the Chassis Ground
screw to earth ground by connecting to a
ground rod (a metal rod pounded into the
earth) or other proper service entrance
ground.
