grounding connections are made.
Verify that a licensed electrician has attached the cable lugs provided with the router
2.
to the grounding cable.
Connect the grounding cable to a proper earth ground for both external power sources.

CAUTION:
Do not substitute metric bolts such as M6 for the 1/4-20 UNC
bolts that screw into the grounding points; bolts other than 1/4-20 UNC
bolts can strip the threading in the grounding points.
Secure the grounding cable lug over the grounding points on the bottom rear of the
