MX10004 Site Electrical Wiring Guidelines
"MX10004 Environmental Requirements and Specifications" on page 81
describes the factors you must
consider while you plan the electrical wiring at your site.
CAUTION: It is particularly important to provide a properly grounded and shielded
environment and to use electrical surge-suppression devices.

Signaling limitations
To ensure that signaling functions optimally:
•
Install wires correctly.
Improperly installed wires can emit radio interference.
•
Observe the recommended distances, and avoid passing 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.
Radio frequency interference
(RFI)
To reduce or eliminate the emission of RFI from your site wiring:
•
Use a 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 if you must exceed the recommended distances.
