Install a lightning surge protector (Canada)
Use the procedure in this section to install a lightning surge protector (Canada only).
Install the lightning surge protector for the outdoor omnidirectional external antenna to protect it
from electrical surges. The recommended lightning surge protector is part number A0382082.
Refer to the installation instructions from the manufacturer for more details on its installation. To
install a lightning surge protector, follow these steps:
1 Install the surge protector on the interior wall as close as possible to the entry point of the
coaxial cable from the outdoor antenna.
Figure 176 shows where to locate the surge protector. Follow the installation instructions
provided with the surge protector.

2 Attach the ground lead to an approved ground, before you connect the ground lead to the surge
protector.
The recommended wire gauge is 6 AWG (4 mm). Connect the ground lead to the building
ground. Do not connect to a ground rod or series of ground rods. If you cannot connect the
ground lead to the building ground, connect the ground lead to the metal frame of the building.
The connection must be no more than 2 m (6.5 ft.) to 3 m (10 ft.) long.
You can connect the ground lead to the 120 V ac conduit (which is connected to the building
ground). However, Nortel Networks does not recommend using the 120 V ac conduit.
3 Route and connect the coaxial cable from the outdoor antenna to the surge protector.
