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.
