SRX210 Services Gateway Site Electrical Wiring Guidelines
Table 1 describes the factors you must consider while planning the electrical wiring for the services gateway at your site.
It is particularly important to provide a properly grounded and shielded environment and to use electrical surge-suppression devices.
For devices with AC power supplies, an external surge protective device (SPD) must be used at the AC power source.
Table 1: Site Electrical Wiring Guidelines for the Services Gateway
Site Wiring Factor | Guideline |
---|---|
Signaling Limitations | To ensure that signaling functions optimally:
|
Radio Frequency Interference (RFI) | To reduce or eliminate the emission of RFI from your site wiring:
|
Electromagnetic Compatibility (EMC) | Provide a properly grounded and shielded environment and use electrical surge-suppression devices. Strong sources of electromagnetic interference (EMI) can cause the following damage:
Note: If your site is susceptible to problems with EMC, particularly from lightning or radio transmitters, you may want to seek expert advice. |
To comply with intrabuilding lightning/surge requirements, the intrabuilding wiring must be shielded. The shielding for the wiring must be grounded at both ends.
