Electrical Caution
Before crimping the power wires to the terminal blocks, ensure that the power wires
are not connected to the DC outlet.
Notes:
•
To ensure power redundancy, both PEM modules must be connected to
the power source.
•
To meet NEBS requirements, the device must be connected to the DC
power using the cables specified in this section.

To connect power using a DC terminal block crimp connector, take
these 3 steps:
1.
Remove the terminal block screw from the chassis power socket (labeled
DC IN
), by
unscrewing the two screws located on the front of the terminal block.
2.
Connect the two insulated wires to the correct DC power outlet. Ensure that the
connections to the DC power outlet maintain the correct polarity (positive / negative).
3.
Insert the supplied DC power feed cable crimped to the terminal block, into the DC
inlet (labeled
DC IN
). Ensure that the hook on the terminal block snaps into the groove
above the DC inlet.
