CAUTION: The maximum torque rating of the terminal studs on the DC PDM
is 25 lb-in. (33.89 Nm). The terminal studs might be damaged if excessive torque
is applied. Use only a torque-controlled driver or socket wrench to tighten nuts
on the DC PDM terminal studs.
NOTE: The DC PDMs in slots PDM0/Input0 and PDM1/Input1 can be powered by
dedicated power feeds derived from feed Aor feed B. This configuration provides the
commonly deployed A/B feed redundancy for the system to balance the power draw.

10. Route the positive and negative DC power cables through the left and right sides of the cable restraint.
11. Tighten the cable restraint captive screw to hold the power cables in place.
CAUTION: The maximum torque rating of the cable restraint screws on the DC
PDM is 25 lb-in. (33.89 Nm). Use only a torque-controlled screwdriver to tighten
screws on the DC PDM cable restraint.
12. Verify that the power cables are connected correctly, that they are not touching or blocking access to
router components, and that they do not drape where people could trip on them.
13. Repeat Steps 3 through 12 for the remaining PDMs.
