To buffer the bus voltage. If a complete mains failure occurs, an external lead gel battery with a voltage of DC 12 V (SELV) can be connected to the REG power supply for buffering.
The lead gel battery is recharged or maintained in its charged state by integrated charging electronics.
A binary input can be connected in order to register the operational statuses (mains voltage, error warning, battery operation).
