GuidelineSite Wiring Factor
To reduce or eliminate the emission of RFI from your site wiring:
•
Use twisted-pair cable with a good distribution of grounding
conductors.
•
Use a high-quality twisted-pair cable with one ground conductor
for each data signal when applicable, if you must exceed the
recommended distances.
Radio Frequency
Interference (RFI)
Provide a properly grounded and shielded environment and use
electrical surge-suppression devices.
Strong sources of electromagnetic interference (EMI) can cause
the following damage:
•
Destroy the signal drivers and receivers in the device
•
Conduct power surges over the lines into the equipment, resulting
in an electrical hazard
NOTE: If your site is susceptible to problems with EMC, particularly
from lightning or radio transmitters, you may want to seek expert
advice.
Electromagnetic
Compatibility (EMC)
CAUTION: To comply with intrabuilding lightning/surge requirements, the
intrabuilding wiring must be shielded. The shielding for the wiring must be
grounded at both ends.
