cables are found in Appendix B.

Routing Power and Signal Wiring

Be aware that when you route power and signal wiring on a machine
or system, radiated noise from nearby relays, transformers, and other
electronic drives, can be induced into motor or encoder feedback,
communications, or other sensitive low voltage signals. This can cause
system faults and communication problems.

Refer to Chapter 1 for examples of routing high and low voltage
cables in wireways. Refer to System Design for Control of Electrical
Noise
(publication GMC-RM001x-EN-P) for more information.
