Distance limitations for signaling—Improperly installed wires can emit radio
interference. In addition, the potential for damage from lightning strikes increases
if wires exceed recommended distances or if wires pass between buildings. The
electromagnetic pulse (EMP) caused by lightning can damage unshielded
conductors and destroy electronic devices. If your site has previously experienced
such problems, you might want to consult experts in electrical surge suppression
and shielding.
Radio frequency interference—You can reduce or eliminate the emission of radio
frequency interference (RFI) from your site wiring by using 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.
Electromagnetic compatibility—If your site is susceptible to problems with
electromagnetic compatibility (EMC), particularly from lightning or radio
transmitters, you might want to seek expert advice. Strong sources of
electromagnetic interference (EMI) can destroy the signal drivers and receivers
in the routing platform and conduct power surges over the lines into the
equipment, resulting in an electrical hazard. It is particularly important to provide
a properly grounded and shielded environment and to use electrical
surge-suppression devices.
