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.
