Grounding The Router - HP MSR954 Series Installation Manual

Grounding the router

CAUTION:
 Correctly connecting the grounding cable is crucial to lightning protection and EMI protection. When
you install and use the router, first ground the router reliably.
 Ensure a minimum resistance of 5 ohms between the router and the ground.
The router provides only a ring terminal. No grounding cable is provided with the router. Purchase a
grounding cable yourself.
Grounding the router with a grounding strip
1. Remove the grounding screw from the grounding hole in the chassis.
2. Use the grounding screw to attach the ring terminal of the grounding cable to the grounding
hole.
3. Use a screwdriver to fasten the grounding screw.
4. Connect the other end of the grounding cable to the grounding strip.

Grounding the router by burying a grounding conductor in the earth ground
If the installation site does not have any grounding strips, but earth ground is available, hammer a
0.5 m (1.64 ft) or longer angle iron or steel tube into the earth ground to act as a grounding
conductor.
Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion
protection.
