Most connections come pre-terminated through the use of the wiring harnesses.
Communication wiring must be terminated directly to the FAC . Power input wiring is required for the FAC in addition to the existing power input wiring used for the base of the DX controller.
Figure 1. Wiring connections
The replacement controller has fewer I/O terminal points than the original DX controller.
Note: For most
applications, you may use the existing DX mounting base terminal
blocks as a termination point for jumper wiring to bring these extra
points to IOM
modules.
