Conduit Openings
1. Conduit openings in the top and/ or bottom
end walls should be completed before the
enclosure is mounted to the wall.
2. It may· be easier to remove the enclosure end
walls to make the conduit openings. Remove
the door hinge screws and then detach the
door.
3. Remove either the top or bottom end wall, but
not both, since side wall stability would be
greatly reduced. Make the conduit openings in
the removed end wall. Replace the end wall.
Ensure that all mounting screws are replaced
and tight­ened to 4 0-50 lb-in torque.
4 . If required, remove the other end wall, make
the conduit openings, and replace the end wall,
as in step 3.
5. For easier cable and device installation, do not
reattach the door until installation is complete.
