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. 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 rated circuit
breakers will be required between the inverter/
charger and the loads.
Feed one or two three-conductor AC input
wire(s) through the strain relief and into the AC
INSTALLATION
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 choose to use butt splices
(not included) to make the wire connections.
AC Output: Depending on the model you
have, feed one or two three-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.
