Guideline
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.
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.
