This usually results from the presence of high voltage or long, close-spaced
conductors. When control lines are closely spaced with lines carrying large currents,
the coupling of magnetic fields can also occur. Use shielded cables to help minimize
noise. Potential noise generators include switching components relays, solenoids,
motors, and motor starters.
Refer to the relevant Federal, State/Provincial, and local electric codes which
provides data such as the size and types of conductors, color codes and connections
necessary for safe grounding of electrical components. It is recommended that the
high voltage and low voltage cabling be separated and dressed apart. In particular,
the AC cables and switch wiring should not be in the same conduit with all
communication cables.
