2.3 Connecting the Ground Wire
Caution:
Properly connect the ground wire before connecting other cables and
shorten it as much as possible to prevent the router and the connected
device from getting damaged during periods of lightning activities.
The grounding screw of the chassis PGND is located on the rear
panel. Connect this screw to the earth ground using a ground wire.
The grounding resistance must not be greater than 5-ohm.
