Step 5: The wiring enters the inverter through
the entry/exit plate as shown to the right. The
rubber grommets have a solid, thin membrane,
so that unused ones continue to seal the opening.
To create an opening, use a sharp knife and
carefully cut an “X” in the center of the
grommet as shown. Be especially careful to
avoid cutting into the thick outer ring, so that the
wiring will have a cushion from contacting the
metal plate.
NOTE: Some inverter models will have a
wiring box for NEMA rating compliance. Make
sure the wire entry to the NEMA box also has
protective cushion from chaffing of insulation.
Before proceeding, please study the caution and warning messages below.
