20.1.3 Guidelines when knocking out knockout holes
NOTICE
Precautions when making knockout holes:
▪ Avoid damaging the casing.
▪ After making the knockout holes, we recommend you 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.
