Site Electrical Wiring Guidelines for EX Series Switches

Table 37 on page 94 describes the factors you must consider while planning the electrical wiring at your site.

WARNING: It is particularly important to provide a properly grounded and shielded
environment and to use electrical surge-suppression devices.
Table 37: 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:
	• Improperly installed wires cause radio frequency interference
	(RFI).
	• Damage from lightning strikes occurs when wires exceed
	recommended distances or pass between buildings.
	• Electromagnetic pulses (EMPs) caused by lightning
	damages unshielded conductors and electronic devices.
Radio frequency interference	To reduce or eliminate radio frequency interference (RFI) from
	your site wiring, do the following:

• Use twisted-pair cable with a good distribution of grounding conductors.

• If you must exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.
