Table 44: Site Electrical Wiring Guidelines for the Services
Gateway
(continued)
Guideline
Site 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.
