Active Running Reserve Battery
A running reserve battery (type BP ETC R 24 V / 2.3 Ah) can be connected to the ETC
to provide all functions during mains power failure. The battery is fully controlled by the
ETC which means that it is charged by the ETC and protected against total discharge.
The battery is disconnected at approximately 90 % of the nominal voltage. The ETC will
then switch to passive running reserve.
Caution:
A running reserve battery connected to the ETC will only be activated once
the mains supply has been switched on again. This also applies to charged
batteries.
