Nokia RoofTop™ Wireless Router Installation Guide

5.2.2 To prepare and install grounding

Grounding is only installed where the existing grounding system
NOTE:
is not sufficient for router grounding purposes.
Because antennas are elevated metal objects with connections to ground,
they attract lightning.
Attaching an effective ground to the router provides a path for the
lightning.
1.
Connect the grounding box connector marked "Surge" towards the
antenna and the connector marked "Protected" to the Network/ Power
Unit (NPU) end of the cabling.
2.
Protect the connections as previously described, using
weatherproofing tape.
3.
Locate the lightning arrestor close to the point of entry to the home.
4.
Provide a good, very low resistance wire connection from the
wireless router to the ground.
5.
Use #12 copper wire connected to the router grounding clamp and a
ground rod next to the building.
