CAUTION: Before router installation begins, a licensed electrician must attach
a cable lug to the grounding and power cables that you supply. A cable with
an incorrectly attached lug can damage the router.
To ground AC-powered and DC-powered routers, connect a grounding cable to earth
ground and then attach it to the chassis grounding points using two screws. The left pair
of grounding points fits M6 screws (European), and the right pair fits UNC 1/4–20 screws
(English). The grounding points are spaced at 0.625-in. (15.86-mm) centers. The
accessory box shipped with the router includes the cable lug that attaches to the
grounding cable (see Figure 47 on page
the grounding cable to the right pair of grounding points.
WARNING: The router is a pluggable type A equipment installed in a restricted
access location. It has a separate protective earthing terminal (Metric [–M6]
and English [–¼-20] screw ground lugs) provided on the chassis in addition
to the grounding pin of the power supply cord. This separate protective earth
terminal must be permanently connected to earth.
