Installation Procedures
Step 5
Insert the end of the grounding wire into the grounding receptacle, which is the bottom receptacle in the
terminal block on the PEM (see
Figure 4-7
). The stripped part of the wire must be fully inserted into the
terminal block so that no bare wire is exposed.
Step 6
Ensure that no wire strands are left outside the connector.
Step 7
Using the screwdriver and a clockwise motion, tighten the ground screw in the terminal block. Gently tug on
the wire to ensure that it is firmly in place.

Step 8
Make sure that the other end of the grounding wire is connected to ground at the DC power source.
Step 9
If you are connecting two power sources to the Cisco 6260 system, repeat
Step 2
through
Step 8
for the
second PEM.
Warning
Only a DC power source that is isolated from the AC main power source with reinforced insulation,
and that complies with the other safety extra-low voltage (SELV) requirements in UL1950, CSA 950 3rd
Edition, EN 60950, and IEC950, can be connected to a Cisco 6260 system. This requirement ensures that
in a catastrophic power source fault condition, hazardous voltages are not present on power
terminals and connectors.
