Table 31: Site Electrical Wiring Guidelines (continued)
GuidelinesSite Wiring Factor
To reduce or eliminate RFI from your site wiring, do the following:
•
Use a twisted-paircablewith 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 device
•
Electrical hazards as a result of power surges conducted over
the lines into the equipment
Electromagnetic compatibility
