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 1-5 for 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 1-7 for 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 1-6 for 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.
