Signal interface connector
Figure 11 shows the pin assignment of the signal interface connector. This connector is used to interface all the control, alarm and monitoring signals with the power shelf that, in turn, interfaces these with the Controller. The control inputs are activated by a ground (BAT RTN) signal. The alarms are extended by relay contacts and are isolated from each other and from the chassis. All contacts are rated 60 V DC and 0.5 A.
