Enclosure Grounding
There are two separate methods for grounding the Overfill Alarm. Ensure that the ground connection is made in
accordance with all local codes.
If using a properly grounded rigid metal conduit or equivalent to enclose the external wiring for the Overfill Alarm,
th
e ground hub that terminates the conduit provides an adequate grounding provision for the Overfill Alarm.
If using a ground wire within the conduit, terminate the ground wire on the grounding stud located in the bottom of
the enclosure. Ensure that a star washer is between the enclosure and the lug attached to the ground wire and
that the lug is secured in place by the included KEPS nut (see Figure
5).
