Input and Output wiring terminations of XM modules land on the Terminal Board (TB) assemblies on the left or right edges or bottom of the backplane.
If you reuse the enclosure, install the terminal strips where TB assemblies were removed to align with existing wiring. You need to fabricate additional wire lengths and route them to the appropriate I/O terminals on the replacement devices.
Line power and N2 Network connections connect to the top of the backplane assembly.
