Here are some recommendations on how to reduce electromagnetic noise on
the communications connections:
•
Careful wire routing helps reduce or minimize electrical noise. Route
incoming power to the terminal by a separate path from the
communications cables.
•
Do not run communications wiring and power wiring in the same conduit.
•
Where communications and power wiring must cross, make their
intersection perpendicular.
•
Proper grounding helps to reduce the effects of noise due to
Electromagnetic Interference (EMI). To avoid problems caused by EMI,
all cables must be shielded and grounded at one end. Grounding is also
an important safety measure in electrical installations.
