CAUTION: It is particularly important to provide a properly grounded and shielded
environment and to use electrical surge-suppression devices.

Guidelines
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.
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.
