Disconnecting Power and Replacing a PM on a CDE200
Warning
The PM connectors and PMs are not hot-swappable. You must disconnect the power source from the
building before disconnecting PM wires or removing PMs from a CDE.
Should you need to replace a PM, you must first disconnect DC power and remove the PM from the CDE
chassis. Perform the following steps:
Step 1 Remove the +Return (red) and –48 VDC (black) DC power wires from your power source.
Step 2 Remove the PM ground wires (green and yellow) from the PM ground stud.
Step 3 Loosen the screw and press the latch to release the PM from the chassis. Pull the handle and gently slide
the PM from the slot.
Step 4 Insert a new PM in the slot and make sure it is completely seated in the CDE.
Step 5 Reconnect the PM ground wires (green and yellow) to the PM ground stud as described in Step 2 of the
“Connecting DC Power to a CDE200” section on page D-2.
