Inserting and Removing Rating Plug from Trip Unit
Steps 1 through 7.
Prior to inserting or removing a rating plug, check to see that
the breaker is in the “Open” position.The breaker should
always be in the “Open” position when a rating plug is not in
the trip unit.The trip unit will default to the lowest possible
settings if a rating plug is not installed.
To prevent the insertion of a rating plug into a trip unit for
which it is not intended, the rating plug connector on the trip
unit has been keyed to reject incorrect plugs.
1. Check label on the rating plug.
Before attempting to insert the rating plug, check the label on
the rating plug label to verify that it is the correct plug for the
trip unit. If it is not a correct plug, the pins on the plug will not
mate with the receptacle in the trip unit.
2. Remove two (2) retaining screws from the plexiglass cover.
Inserting and removing the rating plug requires the removal of
the clear plexiglass cover.To remove the cover, unscrew the
two screws that hold it in place, gently pry one end of the
cover loose with a small screwdriver, and lift off.
3. Remove plexiglass cover.

rating plug into trip unit.
