Connecting DC Power to a CDE200
The CDE200 ships fully populated with two DC PMs installed in the PM slots on the rear of the chassis;
two DC power cables are shipped separately. The chassis has one building ground stud and one PM
ground stud. The minimum cabling requirement for connecting DC power to a CDE200 is one PM
connect, but it is recommended that you use both PM connects.
Figure D-2 shows the rear view of a
fully-connected CDE200 and provides the location of the ground studs and PMs.

Connect DC power to the CDE200 by performing the following steps:
Caution Make sure the DC power wires are not attached to the DC power source until all the ground wires are
connected on the CDE.
Step 1 Insert a blue DC power cable connector into the blue port on each PM, making sure it is completely
seated.
Step 2 Attach the ground wires from PM 1 and PM 2 to the PM ground stud:
a. Remove the nut and star washers from the PM ground stud.
b. Place the ring lug at the end of the ground wires (green and yellow) attached to the DC power cable
connector over the PM ground stud in the following order and secure with the nut (see
Figure D-3):
