Installing the Inverter/Charger

Step 3: Connecting the AC Input and AC Output Wires

FIRE, ELECTRICAL SHOCK, AND ENERGY HAZARDS

Make sure wiring being connected to the inverter/charger is disconnected (physically or by opening the breaker) from all electrical sources before handling. All wiring must be done in accordance with local and national electrical wiring codes.

Failure to follow these instructions will result in death or serious injury.

General AC Wiring Considerations

AC and DC Wiring Separation Do not mix AC and DC wiring in the same conduit or panel. Consult the applicable installation code for details about DC wiring and AC wiring in vicinity to each other.

AC Input and Output Isolation The AC input and output circuits of this inverter/charger are isolated from each other when in invert mode to ensure safe operation. This isolation must be maintained in the installation, by being sure not to connect AC input and output wiring to a common point. For example, do not route the AC input and output neutrals to a common neutral bus.

AC Wiring Compartment For your reference, the AC wiring compartment is shown in Figure 2 on page 21.

AC Knockouts There are two 1" trade-size knockouts on the front panel of AC wiring box. Use the same trade size of strain relief as the trade size of the knockout(s) you are using.

AC Wiring Terminals The AC wiring terminals accept cables of a specific size. See “AC Wiring” on page 9 for required sizes.
