WARNING: The wiring color code of the power cables depends on the color coding
of the DC power source installed at your site. Color code standards for DC wiring do
not exist. To ensure that the correct polarity is connected to the router power units,
confirm the connection of the power cables to the + (positive) and – (negative) leads
at the power source.
NOTE: Loosen the top and bottom thumbscrews (using a No. 2 Phillips screwdriver,
if necessary)
Place the grounding cable lead on one of the grounding studs and tighten the
nuts to secure the connection.
Connect the other end of the ground cable to the appropriate ground termination
lead.
Repeat Steps 3–4 for the remaining grounding stud.
Be sure you have completed "Task 1: Turn Off All Router Power" on page 54
and "Task 2: Connect the Grounding Cables" on page 54.
If applicable, loosen the screws from the clear power input module cover and
