Attaching the Ground Cable to the Access Point
To protect the device from lightning strikes and against electrostatic
discharge (ESD), attach the ground cable to the access point.
Guidelines Review the following guidelines before attaching the ground cable to the
access point:
 Before installing the mounting base to the access point, attach the
ground cable to the access point.
 Connect the ground cable straight to the earth ground; cut off the
extra length of the ground cable.
 Prevent the ground cable from being sharply bent, looped, or
coiled.
 Connect the surge protector ground cable and the equipment
ground to a single common ground. The equipment ground
includes power ground and telecommunications ground.
 The recommended earth ground impedance is less than 1.0 ohm.
 Measure the ground impedance at the point where the surge
protector ground cable, not at the ground rod.
 If you provide your own ground cable, use a 10 AWG or larger
stranded wire as a ground cable.
