Connecting the Trip Unit Wiring Harness

1. Join the four-pin connector on the trip unit har-

ness to the four-pin connector on the flux shifter.

2. Connect the harness leads to the screw terminals

on each CT, as shown in Figure 16. The black wire

(tap) connects to the left terminal and the white

wire (common) to the right terminal.

3. Use the wire ties provided to tie the harness back

against the frame. The harness should be tied to

the holes in the fiber barriers at each CT. Ensure

that the wiring will not interfere with any moving

parts.
