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:
The AC input and output may need to be protected with branch-rated circuit
breakers of maximum 60 Aac size to meet applicable code requirements.
IMPORTANT:
Applicable codes may prevent grid-interactive inverters from using an input circuit
breaker larger than 40 amps. Confirm local requirements before installation.
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 size
is #6 AWG (16 mm) or 0.021 in wire. This is also the largest size that the terminal will accept.
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 60 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.
