Installing a Lightning Arrestor
Overvoltage transients can be created through lightning static discharges, switch processes, direct contact
with power lines, or through earth currents. The Cisco Aironet AIR-ACC245LA-N Lightning Arrestor limits
the amplitude and duration of disturbing interference voltages and improves the over voltage resistance of
in-line equipment, systems, and components. A lightning arrestor installed according to these mounting
instructions balances the voltage potential, thus preventing inductive interference to parallel signal lines within
the protected system.
