Installation
18 900-0166-01-01 Rev A
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
 This unit meets the IEC requirements of Protection Class I.
 The unit must be connected to a permanent wiring system that is grounded according to
the IEC 60364 TN standard.
 The input and output circuits are isolated from ground. The installer is responsible for
system grounding according to all applicable codes.
 For safety, the neutral and ground conductors should be mechanically bonded. OutBack
does not bond these conductors within the inverter. Some codes require the bond to be
made at the main panel only. Make sure that no more than one bond is present in the AC
system at any time.
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 provides the bond.
IMPORTANT:
Most OutBack products are not designed for use in a positive-grounded system. If it is
necessary to build a positive-grounded system with OutBack products, see the
