Juniper MX10004 - MX10004 Site Electrical Wiring Guidelines

MX10004 Site Electrical Wiring Guidelines
"MX10004 Environmental Requirements and Specicaons" on page 81 describes the factors you must
consider while you plan the electrical wiring at your site.
CAUTION: It is parcularly important to provide a properly grounded and shielded
environment and to use electrical surge-suppression devices.
Table 30: Site Electrical Wiring Guidelines
Site Wiring Factor Guidelines
Signaling limitaons To ensure that signaling funcons opmally:
• Install wires correctly.
Improperly installed wires can emit radio interference.
• Observe the recommended distances, and avoid passing wires between
buildings.
The potenal for damage from lightning strikes increases if wires exceed
recommended distances or if wires pass between buildings.
•
Shield all conductors.
The electromagnec pulse (EMP) caused by lightning can damage unshielded
conductors and destroy electronic devices.
Radio frequency interference
(RFI)
To reduce or eliminate the emission of RFI from your site wiring:
• Use a twisted-pair cable with a good distribuon of grounding conductors.
• Use a high-quality twisted-pair cable with one ground conductor for each
data signal if you must exceed the recommended distances.
