AC Wiring
The AC wires route through the strain
relief mounted in holes on the front of the unit.
Use a screwdriver to remove the screws
which secure the AC wiring compartment
cover plate. Depending upon which model you
have, there can be one or two AC inputs and
one or two AC outputs within the AC wiring
compartment. The labeling for the pigtails is on
the front of the unit and is visible when the
cover plate is removed. Note: Green wires are
connected to the AC Ground Strip.

Conventional metal strain reliefs are
provided. These can be replaced with plastic
strain reliefs for additional corrosion resistance
or 3/4 inch conduit fittings if the wiring will be
routed through a conduit.
Appropriate wire gauges must be used
throughout the installation. Refer to NEC
specifications.
AC Input:
All inputs from other AC
sources must be protected by branch circuit
rated circuit breakers.
In the United States, no additional circuit
breakers are required between the inverter/
charger and the loads if the service to the
inverter/charger is protected by a 20 ampere
branch circuit rated breaker. This also applies
to Dual Input models where the inputs may be
20 amperes each. In Canada, 15 ampere
branch circuit(s) maximum shall provide the
service.
If a 30 ampere service supplies the
inverter/charger, additional 20 ampere (15
ampere in Canada) maximum branch circuit
INSTALLATION
rated circuit breakers will be required between
the inverter/charger and the loads.
Feed one or two 3-conductor AC input
wire(s) through the strain relief and into the AC
wiring compartment. Allow 6 inches of
individual insulated black, white and green wire
to work with. Strip 1/2 inch of insulation off
each conductor and connect to the pigtails:
Black to Black, White to White, and Green to
AC Ground Strip.
Use the wire nuts provided to make the
wire connections. You may chose to use butt
splices (not included) to make the wire
connections.
AC Output:
Depending on the model you
have, feed one or two 3-conductor AC output
wire groups for the two branch circuit loads
through its strain relief. Remember to allow 6
inches of individual insulated black, white and
green wire to work with. Strip 1/2 inch of
insulation off each conductor and connect to
the pigtails: Black to Black, White to White,
and Green to AC Ground Strip.
Tug firmly on each connection to make
sure they are secure. Later, if the unit is not
operating properly, check these connections
first. Carefully tuck the wires into the AC wiring
compartment. Replace the cover plate.
