SRX100 Services Gateway Site Electrical Wiring Guidelines
Table 32 on page 115 describes the factors you must consider while planning the
electrical wiring for the services gateway at your site.
CAUTION: It is particularly important to provide a properly grounded and shielded
environment and to use electrical surge-suppression devices.
Table 32: Site Electrical Wiring Guidelines for the Services Gateway
GuidelineSite Wiring Factor
To ensure that signaling functions optimally:
■
Install wires correctly.
Improperly installed wires can emit radio interference.
■
Do not exceed the recommended distances or pass wires between buildings.
The potential for damage from lightning strikes increases if wires exceed recommended
distances or if wires pass between buildings.
■
Shield all conductors.
The electromagnetic pulse (EMP) caused by lightning can damage unshielded conductors
and destroy electronic devices.
Signaling Limitations
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.
