Knockout Preparation
Knockout preparation should be done before mounting either the inverter or the
Long AC Conduit Box.
1. Remove the appropriate knockouts from the AC side of the inverter for
cabling from the Long AC Conduit Box terminal block to the inverter
terminal block. See Figure 2-5 for the size and locations of the knockouts on
the Sine Wave Plus Inverter Charger.
2. Remove the appropriate knockouts from the Long AC Conduit Box for wire
runs from utility and/or inverter panels, a generator, and/or additional
inverters. See Figure 2-6 for the locations of the knockouts on the Long AC
Conduit Box.
3. If additional circuit breakers are to be added to the Long AC Conduit Box,
remove one knockout on the top cover for each additional circuit breaker to be
installed. See Figure 2-6 for the locations of the knockouts on the Long AC
Conduit Box top cover.
4. Ensure that there are no metal shavings in the Long AC Conduit Box or
inverter before proceeding with the rest of the installation.
5. Install bushings in the knockout holes to protect the wires from damage.
Square D™ filler plates (QOFP) may be used to refill a knockout panel if the
knockout is no longer used or removed in error.

Important:
If larger knockouts are required in the Long AC Conduit Box, an
electricians knockout punch may be used for larger size knockout holes if
necessary.
