Site Electrical Wiring Guidelines

Table 1 describes the factors you must consider while planning the electrical wiring at your site.

Warning:

You must provide a properly grounded and shielded environment and use electrical surge-suppression devices.

Avertissement Vous devez établir un environnement protégé et convenablement mis à la terre et utiliser des dispositifs de parasurtension.

Table 1: Site Electrical Wiring Guidelines
Site Wiring Factor	Guidelines
Signaling limitations	If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding: Radio frequency interference (RFI) because of improperly installed wires. Damage from lightning strikes occurring when wires exceed recommended distances or pass between buildings. Damage to unshielded conductors and electronic devices as a result of electromagnetic pulses (EMPs) caused by lightning.
Radio frequency interference	To reduce or eliminate RFI from your site wiring, do the following: Use a twisted-pair cable with a good distribution of grounding conductors. If you need to exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal, when applicable.
Electromagnetic compatibility	If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice. Strong sources of electromagnetic interference (EMI) can cause: Destruction of the signal drivers and receivers in the device. Electrical hazards as a result of power surges conducted over the lines into the equipment.
