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.
6 Reattach the service cover.
7 Connect an earth leakage circuit breaker and fuse to the power
supply line.
