Connecting status information and RS232 links
The status information (see figure 2) is available on the DB9 socket connectors. The pins are as follows:
1.earth,
4.operation on mains (as opposed to battery),
5.common,
6.operation on bypass (static switch or manual bypass),
7.low battery warning,
8.operation on UPS,
9.operation on battery.
A remote stopping signal can be transmitted on pin 3 of each DB9: a high status (4 V to 20 V) of a minimum duration of 100 ms causes the
Relay breaking capacity: Vmax = 30 V
lmax = 200 mA
