Installation

Grounding

WARNING: Shock Hazard

The unit must be connected to a grounded, permanent wiring system. If a bond is made between neutral and ground make sure only one bond is present in the AC system at any time. Some codes require the bond to be made at the main panel only.

WARNING: Shock Hazard

For all installations, the negative battery conductor should be bonded to the grounding system at only one point. If the OutBack GFDI is present, it can provide the bond.

IMPORTANT:

OutBack products are not designed for use in a positive-grounded system. If it is necessary to build a positive-ground system with OutBack products, contact OutBack Technical Support at 360.618.4363 before proceeding. Additionally, consult the online forum at www.outbackpower.com/forum/, where this subject has been discussed extensively.

The inverter’s DC ground is a box lug located next to the negative DC battery terminal. 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 before making the ground connection. (See the next page.)

Figure 6 DC Ground Lug

The two Chassis Ground/PE terminals are electrically common. Only one terminal can be used if connecting to an external ground bus. The other terminal may be used if connecting to a device with its own ground wire, such as a generator.
