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.
