8.0 FRONT PANEL DESCRIPTION
The front panel of the DPP2U, 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
