When cables are routed from the unit, a protection
sleeve for the conduits (PG insertions) can be
inserted at the knockout hole.
When you do not use a wire conduit, protect the
wires with vinyl tubes to prevent the edge of the
knockout hole from cutting the wires.

NOTICE
Precautions when making knockout holes:
▪ Avoid damaging the casing and underlying piping.
▪ After making the knockout holes, we recommend to remove the burrs and paint
the edges and areas around the edges using repair paint to prevent rusting.
▪ When passing electrical wiring through the knockout holes, wrap the wiring with
protective tape to prevent damage.
