SECTION 5. INSTALLING THE TRIP
UNIT
The trip unit is attached to the trip unit mounting
bracket. Guide pins in the bracket mate with the
holes on either side of the trip unit box. The guide
pins provide the necessary alignment for the con-
nector engagement. The locking lever engages with
the pin, which is assembled to the trip unit, and
secures the trip unit to the mounting bracket.
Use the following procedure to install the trip unit:
1. Line up the trip unit with the mounting plate.
Insert the guide pins into their holes push on the
trip unit. This will engage the connectors and
release the locking lever, which will move
upward.
2. Verify that the locking lever engaged with the pin
on the rear of the trip unit.
To remove the trip unit, pull the locking lever down
to release the pin on the rear of the unit. Pull the trip
unit straight off the mounting plate.
WARNING: Be sure to perform the continuity test
described in step 1 of Testing in Section 7 before
energizing or performing a primary injection test on
the converted breaker. Failure to do so may result in
damage to the trip unit, wire harness, 36-pin
connector, and CTs.
