The inverter’s DC ground is a box lug located next to the negative DC battery terminal. This lug accepts
up to 1/0 AWG (70 mm or 0.109 in) wire. Local codes or regulations may require the DC ground to be run
separately from the AC ground. Also, if present, it will be necessary to remove the DC Cover or Turbo Fan
before making the ground connection. (See page 20.)

Box Lug
One ground terminal is labeled CHASSIS GROUND.
This terminal connects to an external ground bar or
bus. The other terminal, labeled NEU/GROUND BOND,
is not common with CHASSIS GROUND, but is joined
to it by a copper jumper. No external connection is
made to NEU/GROUND BOND.

As long as the copper jumper is present, the FX
inverter will automatically perform neutral-ground
bond switching.

If removed, the inverter’s neutral and ground will
be isolated.
If only one mobile inverter is present, leave the
copper jumper in place.
If more than one mobile inverter is present, remove
the copper jumper from every Slave unit.
See the inverter Operator’s Manual for the general
operation of neutral-ground bond switching.
See page 22 for more information on the inverter’s
switching function.
