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.
WARNING: 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 106 on page 244 summarizes the specifications for the power cables, which you must supply.

CAUTION: You must ensure that power connections maintain the proper polarity.
The power source cables might be labeled (+) and (–) to indicate their polarity. There
is no standard color coding for DC power cables. The color coding used by the external
DC power source at your site determines the color coding for the leads on the power
cables that attach to the terminal studs on each power supply.
