Communications Wiring
Refer Figure 14 for the following:
1)
Voltage Input
Determine the line side of the breaker and drill and tap a
10-32 hole in each of the three line side poles.
Use #14 SIS wire from the bus taps 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 side of the AC-PRO
+
trip
unit and into the PT Module.
Use cable ties and holders to make a clean installation.
4)
Breaker Position Indication
As an option, connect an unused “a” contact in 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.
