Installation

Knockout Preparation

Knockout preparation should be done before mounting either the inverter or the ACCB.

1.Remove the appropriate knockouts from the AC side of the inverter, for cabling from the ACCB terminal block to the inverter terminal block. See Figure 1-5for the size and locations of the knockouts on the Sine Wave Plus Inverter Charger.

2.Remove the appropriate knockouts from the ACCB for wire runs from utility and/or inverter panels, a generator, and/or additional inverters. See Figure 1-7for the locations of the knockouts on the ACCB.

3.If additional circuit breakers are to be added to the ACCB, remove one knockout on the top cover for each additional circuit breaker to be installed. See Figure 1-6for the locations of the knockouts on the ACCB top cover.

4.Ensure that there are no metal shavings in the ACCB or inverter before proceeding with the rest of the installation.

5.Install bushings in knockouts provided to protect the wires from damage.
