SRX340 Services Gateway Electrical Wiring Guidelines
Table 9 on page 33 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 9: Site Electrical Wiring Guidelines for the SRX340 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.
