5.6.2 Control Wiring
Cables for controlling and monitoring the rectifiers and circuit breakers/fuses must be run from expansion frames to the control unit in the base frame. There are three basic cables used for these functions:
•The AWA-0970 ten-pin ribbon cable connector handles serial communications for rectifier reporting and control. This cable connects to the J1 connector of the DC/DC converter PCB’s (EAA-0111) in each power box frame.
•Circuit breaker reporting in extension power and distribution bays is communicated back to the control unit through the AWA-0972 cable. This cable is connected to J15 on the control unit interface PCB in the base unit and runs to connector J2 on the Alarm Extension PCB (EAA-0072) in the remote bay. Additional bays are connected via the same cable, which connects up to four Alarm Extension PCB’s.
•Fuse reporting is routed from the Fuse Sense PCB (ADV-1204) to the control unit via cable AWA-0967.
Refer to Figure 5-6 for a pictorial representation of multi-bay cable connection. Figure 5-7 shows the information as a wiring diagram.
