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.
CAUTION: The router is a pluggable type A equipment installed in 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.
Table 73 on page 185 summarizes the specifications for the power cables, which you must
supply.
