8.0 FRONT PANEL DESCRIPTION
The front panel of the DCPDU2B, shown in Figure 3 below, consists of the A and B sides
and a center section. The A and B sides can each accommodate up to 10 field installed/
replaceable hydraulic magnetic circuit breakers rated from 2.5A to 200A. The center section
has two green/red LEDs, one for the A side (left) and the other for the B side (right). At the
bottom of this center section is a slot for a wallet and designator card. This card permits the
recording of each output circuit by number.
