Ac Wiring; Figure 12 Ac Terminals - Outback FX Series Installation Manual

AC Wiring

All system wiring must comply with national and local codes and regulations.
The inverter's AC terminal block has six positions for AC wires. The minimum recommended size is #10
AWG (6 mm2) or 0.009 in2 wire. The terminals should be tightened to a torque value of 25 in-lb (2.8 Nm).
AC NEUTRAL OUT
The AC NEUTRAL OUT
terminal connects to
the neutral bus on the
load panel.
AC NEUTRAL IN
The AC NEUTRAL IN
terminal connects to
the circuit breaker or
bus from an AC input
source, such as shore
power or generator.
Do not connect the AC NEUTRAL IN and AC NEUTRAL OUT terminals together.
These terminals are isolated from each other while inverting. When an AC source
is connected, the neutral terminals switch to become electrically common.
The neutral bus from the input source must be kept isolated from the load panel's
output neutral bus. Loads must not bridge the input and output terminals, even if
the inverter does not power them. An example would be an air conditioner with
its hot wire connected to the AC source and its neutral wire connected to the
inverter's output load panel.

WARNING: Shock Hazard

All AC source neutral and ground conductors should be mechanically bonded. The
inverter's neutral and ground conductors should be left isolated. The inverter
performs automatic neutral-ground bond switching during operation.

Ground fault circuit interrupter (GFCI) devices must be installed in a recreational
vehicle wiring system to protect all branch circuits.
WARNING: Fire Hazard
To reduce the risk of fire, do not connect to an AC load center (circuit breaker panel)
having multi-wire branch circuits connected.
IMPORTANT:

The installer is responsible for providing overcurrent protection. Install an
approved 30 Aac circuit breaker on the inverter's output.

This page contains OutBack's recommendations for minimum safe cable sizes.
Other codes, particularly for mobile or marine applications, may supersede
OutBack's recommendations. Consult applicable codes for final size requirements.

Installation
AC HOT OUT
The AC HOT OUT terminal
connects to the output load
panel. The terminal can
carry up to 30 amps using
the inverter's transfer relay.
Use the inverter wattage to
size the actual maximum
output load. Size the circuit
breaker 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.
