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 9, 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 connector, as
shown in Figure 10. 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 11.
