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. \n \nThe lead gel battery is recharged or maintained in its charged state by integrated charging electronics. \n \nA binary input can be connected in order to register the operational statuses (mains voltage, error warning, battery operation). \n
