Signaling If your site experiences any of the following problems, consult experts in electrical surge
limitations 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 damage unshielded conductors and
electronic devices.
Radio To reduce or eliminate RFI from your site wiring, do the following:
frequency
•
Use a twisted-pair cable with a good distribution of grounding conductors.
interference
•
If you must exceed the recommended distances, use a high-quality twisted-pair cable with
one ground conductor for each data signal when applicable.
Electromagnet If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly
ic from lightning or radio transmitters, seek expert advice.
compatibility
Some of the problems caused by strong sources of electromagnetic interference (EMI) are:
•
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
