panel circuit breaker CB1 protects the +28 V dc unfiltered mission

power input to voltage regulator A1. When DC POWER circuit breaker

CB1 is set to the on (in) position, the +28 V dc input at connector

pin J3-X passes through connector pin A1P1-1 to voltage regulator

The lamp adjust inputs from external system equipment

assembly A1.

at connector pins J8-V and J8-X pass through connector pins A1P1-4

and A1P1-5, respectively, to control voltage regulators VR1 and VR2

(figure FO-4). The outputs of voltage regulators VR1 and VR2 pass

through connector pins A1P1-2, A1P1-3, J8-Y, and J8-a to external

system equipment.
