AC Wiring
WARNING: Shock Hazard
 The neutral and ground conductors should be mechanically bonded.
Ensure there is no more than one AC neutral-ground bond at any time.
 Local or national codes may require the bond to be made at the main panel only.
IMPORTANT:
This page contains OutBack’s recommendations for minimum safe cable sizes.
Other codes may supersede OutBack’s recommendations. Consult applicable
codes for final size requirement
s.
All system wiring must comply with national and local codes and regulations.
The FXR inverter’s AC terminal block has six positions for AC wires. The minimum recommended wire
size is 6 mm (#10 AWG) or 0.008 in. Larger wire gauges may be required for specific conditions. The
largest size that can be used with the terminals is 16 mm
(#6 AWG) or 0.021 in wire.
Figure 12 AC Terminals
NEUTRAL
The two NEUTRAL
terminals are
electrically common.
If connecting to an
external neutral bus,
only one terminal
needs to be used. An
external neutral bus is
often located in the
main electrical panel.
Use the other terminal
if connecting to a
device that has its own
neutral wire, such as a
generator.
AC HOT OUT
T
he AC HOT OU
T
terminal connects to the
output load panel.
T
he terminal can carry
up to 30 amps using the
inverter’s transfer relay.
Use the inverter
power to size the actual
maximum output load.
Size the circuit breakers
accordingly.
AC HOT IN
The AC HOT IN terminal brings current from the AC source. It powers both battery
charger and loads. Use the source size to determine actual current draw. Size all
circuit breakers accordingly.
