INSTALLATION

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

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.
