Mounting Instructions for the<br />

Cisco Aironet 340 Series Lightning Arrestor<br />

March 27, 2000<br />

This document <strong>de</strong>scribes the lightning arrestor kit and provi<strong>de</strong>s instructions for mounting the arrestor.<br />

Overvoltage transients can be created through lightning static discharges, switch processes, direct<br />

contact with power lines or through earth currents.<br />

Cisco Aironet lightning EMP protectors limit the amplitu<strong>de</strong> and duration of disturbing interference<br />

voltages. Therefore, these protectors improve the overvoltage resistance of in-line equipment, systems,<br />

and components. The following mounting procedure balances the voltage potential, thus preventing<br />

inductive interference to parallel signal lines within the protected system.<br />

Please note the following warnings to prevent acci<strong>de</strong>nts during the installation of the arrestor.<br />

Warning Disconnect or switch off in-line equipment when installing or inspecting lightning<br />

protectors during an electrical storm.<br />

Warning When connecting lightning protectors, make sure that the succeeding equipment and<br />

components are disconnected or turned off.<br />
