Table 21: Site Electrical Wiring Guidelines
GuidelinesSite Wiring Factor
If your site experiences any of the following problems, consult experts in
electrical surge suppression and shielding:
•
Improperly installed wires cause radio frequency interference (RFI).
•
Damage from lightning strikes occurs when wires exceedrecommended
distances or pass between buildings.
•
Electromagneticpulses (EMPs) caused by lightning damage unshielded
conductors and electronic devices.
Signaling limitations
To reduce or eliminate RFI from your site wiring, do the following:
•
Use a twisted-pair cable with a good distribution of grounding
conductors.
•
If you must exceed the recommended distances, use a high-quality
twisted-pair cable with one ground conductor for each data signal when
applicable.
Radio frequency
interference
If your site is susceptible to problems with electromagnetic compatibility
(EMC), particularly from lightning or radio transmitters, seek expert advice.
Some of the problems caused by strong sources of electromagnetic
interference (EMI) are:
•
Destruction of the signal drivers and receivers in the switch
•
Electrical hazards as a result of power surges conducted over the lines
into the equipment
