Table 9: Site Electrical Wiring Guidelines for the SRX340 Services
Gateway (continued)
GuidelineSite Wiring Factor
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.

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.
