Installation

Wiring

It will be necessary to remove knockouts from the AC Plate to run wires. The AC Plate has one knockout of
½" size and two knockouts of ¾" size. Install appropriate bushings to protect the wires.
Use copper wire only. Wire must be rated at 75°C or higher.

Grounding

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:
Not all OutBack products can be used in a positive-ground system. If it is necessary to
build a positive-ground system with OutBack products, contact OutBack Technical
Support at +1.360.618.4363 before proceeding. Additionally, consult the online forum
at www.outbackpower.com/forum/, where this subject has been discussed extensively.

or marine applications may supersede OutBack's recommendations. Consult applicable codes for final
size requirements.

Mobile models perform automatic neutral-to-ground bond switching. When this
function is engaged, the chassis ground is electrically common with the output
neutral conductor. When disengaged, the chassis ground is isolated from the AC
system. See pages 17, 21, and 22.
Make sure that no more than one bond is present in the AC system at any time.
