WARNING: For field-wiring connections, use copper conductors only.
WARNING: DC Power cables must not block access to router components
or drape where people could trip on them.
CAUTION: You must ensure that power connections maintain the proper
polarity. The power source cables might be labeled
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.
The accessory box shipped with the router includes cable lugs for 4-AWG (21.2 mm
cable lugs. The cable lugs are dual hole, and sized to fit 1/4-20 UNC terminal studs at
15.86-mm (0.625-in.) center line.

CAUTION: Before router installation begins, a licensed electrician must attach
a cable lug to the power cables that you supply. A cable with an incorrectly
attached lug can damage the router.
