Table 46: Site Electrical Wiring Guidelines for the Services Gateway (continued)
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.
