Communications Wiring
Refer to Figure 18 for the following:
1)
Voltage Input
Determine the line side of the breaker.
Use T-412-1 ring terminals and #14 AWG SIS wire from the
3/8-16 H.C screws (shown in Figure 6) to the 3-pole fuse
block. It is very important to maintain the proper
phasing.
Use #18 MTW wire from the 3-pole fuse block to the PT
Module. Use fiberglass sleeving to protect the wires.
2) Ground Input
Connect a #18 MTW wire from the “Ground” terminal of the
PT Module to the breaker frame.
3)
PT Module Harness
Plug the PT Module cable into the bottom of the AC-PRO
trip unit and the PT Module.
Use cable ties and holders to make a clean installation.
It is very important to make sure the wires will not be
pinched, cut or chaffed by any moving parts or sharp
edges.
4)
Breaker Position Indication
As an option, connect an unused “a” contact from the
breaker auxiliary contacts to the two position input
terminals on the PT Module.
This will provide the breaker open or closed information
to the communications system.
