Make all electrical connections to the assembly in accordance with the job wiring diagram, the
National Electric Code Article 500, and in compliance with the local electrical codes.
Two 3/4" pipe tapped openings are provided in the housing for rigid conduit connections. It is
recommended to insert a chase nipple from inside of the housing to prevent threads from cutting
or damaging wiring.
When wiring, take care to lay all leads in the wiring channel located just under the housing cover
to protect the leads from any sharp edges which may be in the vicinity.
The housing and the edge of the cover are stamped with the letter "O." When replacing the cover,
the letters must be aligned with each other.
Warning: The cover-to-housing orientation must be maintained in order to preserve the
integrity of the seal. Failure to observe this warning can result in injury or death.
