Main Power Breakdown Relay
To be able to distinguish PSU faults from power failure, a main power breakdown relay can be
used. This relay is not included in the AR repeater and has to be mounted outside the
repeater cabinet. The relay intended for this purpose must fulfil the following specifications:
Closing time: Max. 30 milliseconds
Insulation coil/contact: Min. 4KV
A main power connected relay must also be in compliance with valid local regulations. Figure
3-13 illustrates the connection points and Table 3-5 lists the steps for making the connections.

Step Action
1 Connect a currentless closed relay contact to pin AI1 and AIC on the P33 alarm connec-
tor. An alarm is initiated by short-circuiting the pins. For the BMU the main power break-
down cables are connected to pin AI1 and AIC in the P109 port on the FON.
2 Connect the relay coil. It must be supplied from the same fuse as the repeater.
3 After commissioning, select Mains Breakdown in the alarm configuration window in OM-
Online or OMS. Refer to the OM-Online User Manual.
