ATTENTION: To guard against enclosure damage,
align the conduit so as to prevent unnecessary stress on
the enclosure walls.
You can connect conduit to the conduit connector (hub) before or
after the conduit connector is secured into the prepared hole using
the connector locknut. Tighten connector locknut securely to provide
bonding to equipment enclosure.

ATTENTION: To complete the bonding between
grounding bushings and the enclosure, bonding must
be provided in accordance with all applicable codes.
