Rating Plug Installation – Insertion and Removal
11
4. Squeeze plug clips to insert or remove from trip unit.
To insert a rating plug in the trip unit, align the plug with the
plug receptacle and press the plug into place.The clips on the
plug and the compression fit hold the plug in place, eliminat-
ing the need for screws or latches.The plug will “snap” into
place without excessive force. Do not force the rating plug
into place.
To remove a rating plug, squeeze the clips and pull the plug
from the plug receptacle. Since the plug is held in place by
compression, some force will be required to remove the plug.
Do not close the breaker with the rating plug removed from
the trip unit.
5. To replace the cover, bow slightly in the middle, and snap
into place.
After the rating plug has been inserted and the necessary
setting adjustments have been made (see Fault Protection
Adjustments, pages 13-18), replace the cover by sliding the
protective cover into the top lip of the trip unit, bow slightly in
middle, and press down with thumb on bottom to snap cover
into place. Replace the two (2) special retaining screws.
6. Replace two (2) screws retaining the plexiglass cover.
7. The cover may be sealed with a lead seal for tamper evident
protection.
After the cover has been replaced, a wire may be inserted
through the holes in the screws and secured with a meter
seal.This will help prevent tampering.
