Grounding the router
5.4 Grounding the router
Because antennas are elevated metal objects with connections to ground,
they attract lightning.
The Nokia RoofTop Wireless Router has a grounding lug in it. A ground
wire can be attached to it to provide an appropriate and safe path to
ground for the lightning. Additional grounding is only required if the
existing grounding system within the property is insufficient for router
grounding purposes.
Section 810 of the National Electrical Code ANSINFPA No 70-1984
provides information about proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna discharge unit,
connection to grounding electrodes and requirements for the grounding
electrode.
To ground the router:
1.
Connect a ground wire to the grounding lug at the bottom of the
router. The picture below shows the location of the grounding lug at
the bottom of the wireless router.
2.
Run the ground wire from the router to the appropriate electrical
ground.
