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. 
Attaching the grounding cable to the ring terminal 
1.  Cut the grounding cable to the desired length. 
2.  Use the wire-stripping pliers to peel 5 mm (0.20 in) of insulation sheath from one end of the 
grounding cable. 
3.  Add a heat-shrink tubing on the cable. 
4.  Insert the bare metal part of the grounding cable into the ring terminal. 
5.  Use the needle-nose pliers to secure the metal part of the cable in the ring terminal. 
6.  Cover the joint with the heat-shrink tubing, and use a blow dryer to shrink the tubing around 
the cable.
