Installing the Trip Unit Wiring Harness

CAUTION

: Pins in the connectors may come loose in

shipping. Check all wiring harness connectors to
ensure that the pins are tight. Reseat pins as
necessary.

Use the following procedure to install the trip unit
wiring harness to the mounting plate.
1. The wiring harness includes a 36-pin connector,

shown in Figure 8, that must be assembled and

installed onto the trip unit mounting plate before

the trip unit can be installed.

CAUTION:

The adapter bracket must be installed

onto the trip unit 36-pin connector and trip unit
mounting plate as described below. Failure to do so
will result in harness plug failure and the trip unit
will not provide protection. If the converted breaker
is energized or primary injected with the mounting
plate not installed or installed improperly, damage
will result to the trip unit, wire harness, 36-pin
connector, and current sensors. Failure to adhere to
these instructions will void all warranties.

2. Slide the adapter bracket onto the 36-pin con-

nector, as shown in Figure 9. Be sure that the

beveled corners of the trip unit connector are

facing toward the right side, the adapter bracket

slides are in place behind the notches on either

side of the connector body, and the connector’s

tabs align with the notches on the bottom of the

adapter bracket.

3. Hold the adapter bracket tight to the trip unit

connector and bend the two locking tabs on the

adapter bracket over the connector body, as

shown in Figure 10.
