Installing the Wiring Harness

The wiring harness consists of a section for the trip
unit and another for communication. The communi-
cation harness is supplied with all kits, but may not
be required for MicroVersaTrip Plus™ trip units.
Separate and route the wiring harness as follows:

1. The four-pin flux shifter connector and the CT

wire leads should be routed through the wiring

hole in the auxiliary switch mounting plate or

just behind the mounting plate, as shown in Fig-

ure 39. The wiring harness should run along the

inside front edge of the breaker right side frame.

Connect the four-pin connector to its mating

connector on the flux shifter assembly. Tie the

harness away from any moving parts or sharp

edges, as shown in Figure 40.

2. Route the CT wires along the inside bottom edge

of the breaker right side frame toward each pole

assembly and connect to the mating lugs on the

phase sensors, as shown in Figure 41. Be sure to

observe proper polarity, with the white lead

connecting to the tap (X2) and the black lead to

common (X1).
