Adding or Replacing a DC PEM
Figure 7
Connecting Power to the Terminal Block
Step 6
Insert the power lead from the battery –48V power source into the receptacle
labeled – (negative) on the PEM. The stripped part of the wire must be fully
inserted, so that no bare wire is exposed. Use the screwdriver to tighten the
terminal screw to a torque of 1.5 to 1.8 newton meters (13.28 to
15.93 inch-pounds). (Tighten the screws clockwise.)
Step 7
If you are connecting a second power source, repeat
Step 5
and
Step 6
to wire the
second power source to the second PEM.
Step 8
If your chassis contains only one PEM, install a blank faceplate over the empty
power bay.
Warning
Blank faceplates (filler panels) serve three important functions: they
prevent exposure to hazardous voltages and currents inside the chassis;
they confine electromagnetic interference (EMI) that might disrupt other
equipment; and they direct the flow of cooling air through the chassis. Do
not operate the system unless all cards, power modules, and faceplates are
in place.
