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.

Wiring
Warning: Do not operate the
inverter without connecting it
to ground. Electrical shock
hazard may result.
Ground Wiring

If the cable has too much voltage drop, the
inverter may shut down when drawing higher
currents because voltage at the inverter may
drop below 10 volts. If you must use longer
cables choose thicker cables, such as #2 AWG,
and trim the ends of the cable to fit the terminals.
Strip back the insulation about 1/2 inch (1.25cm)
on the end of the cable that connects to the
inverter, exposing the bare cooper conductor.
The other end of the cable that connects to bat-
tery must be terminated with a battery terminal
that clamps to the post on the battery.
CAUTION: Electrical installa-
tions must meet local and
national wiring codes, and
should be performed by a
qualified electrician.
CAUTION: Do not connect the
inverter and another AC source
(such as a generator or utility
power) to the AC wiring at the
same time. The inverter will be
damaged if its output is con-
nected to AC voltage from
another source. Damage can
even occur if the inverter is
switched Off.
CAUTION: Do not connect the
inverter to an AC branch circuit
that has high-power con-
sumption loads. It will not
operate electric heaters, air
conditioners, stoves, and other
electrical appliances that con-
sume more than 1000 watts.
