When you run wires for any significant distance in an electromagnetic field,
electromagnetic interference (EMI) can occur between the field and the signals on
the wires.
Note that:
Bad plant wiring can result in radio frequency interference (RFI).
•
Strong EMI, especially when it is caused by lightning or radio transmitters,
•
can destroy the signal drivers and receivers in the system, and can even create
an electrical hazard by conducting power surges through lines and into the
system.
To predict and remedy strong EMI, consult RFI experts.
This section describes the requirements your site must meet for safe installation
and operation of your WLSE. Ensure that your site is properly prepared before
beginning installation.
When planning your site layout and equipment locations, keep in mind the
precautions described in this section to help avoid equipment failures and reduce
the possibility of environmentally caused shutdowns. If you are currently
experiencing shutdowns or unusually high errors with your existing equipment,
these precautions will help you isolate the cause of failures and prevent future
problems.
