Even if a network setting changes due to power interruption or the like, communication for controlling the operating status of load devices of an uninterruptible power supply is enabled to continue. A network communication system () for the uninterruptible power supply comprises UPS member controllers (and) and a UPS group controller () which are connected in a network () to control the operating status of the load devices () of the uninterruptible power supply (). The UPS group controller () and the UPS member controllers (and) execute data communication according to a predetermined communication protocol (Internet Protocol or the like) through the network (), and these controllers transmit/receive data in which specific identification information issued for each of the UPS member controllers (and) is added to control data as communication data in the data communication according to the predetermined communication protocol.

An uninterruptible power supply and its load device are connected by a network, and the load device to which power is fed by the uninterruptible device properly executes shutdown processing. Communication meansof uninterruptible power suppliesandcommunicate with a load deviceto which they themselves feed power, via a networkUPS storage meansstores a waiting time until the load devicestarts shutdown after it is notified of detection of power abnormality of an AC power supplyNotification meanscauses the communication meansto provide notification of a remaining time until start of shutdown, in a time period until a time period corresponding to the waiting time () stored in the UPS storage meanselapses after power abnormality of the AC power sourceis detected.

Each of connection data, . . . , or, of the downstream side of a socket, . . . , oror a panel board, orin a power supply direction, is generated in a tap, a UPSand, or a terminalor, and each of the connection data is transmitted to a electrical system wiring diagram generating terminal. Then, a wiring diagram is generated, based on connecting informationof the upstream side, which is registered in the generating terminal, and the plural connection data of the downstream sides.

An Uninterrupted Power Supply (UPS) managing system is described for managing a plurality of small UPS devices, the small UPS device are connected to power supply routes between wall sockets and load devices. The UPS managing system comprises a plurality of lower controllers provided corresponding to each of small UPS devices or each of groups which is comprising at least two of said small UPS devices; a communication network for connecting a plurality of said lower controllers each other; and a higher controller connected to said communication network. In addition, each of said lower controllers generates connection information between each of its corresponding small UPS device(s) and each of load device(s) which is powered by said corresponding small UPS device(s), and transmits said connection information to said higher controller. The higher controller also receives and stores said connection information from each of said lower controllers and generates and displays a connection tree which is generated from the stored connection information.
