Abstract
Circuit assembly (1, 1a), uninterrupted power supply unit (1a) with converter part (2) and converter unit (20), central control unit (21) and input for current to be converted and output for converted current and circuit part (3, 4) connected upstream of input of converter part or connected downstream of output of converter part, external control unit (12) connectable to circuit assembly and central control unit (21) configured to receive control instructions from external control unit (12). Circuit assembly can be disconnected from the power supply network rapidly and without repercussions on the network. Every circuit part (3, 4) comprises a decentralized control unit (31, 41), connected to central control unit (21) via communication bus (13), receiving control instructions from central control unit (21). External control unit (12) is connected to communication bus (13) and decentralized control unit (31, 41) is configured to receive control instructions from external control unit (12).
