Abstract: 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 (1) for the uninterruptible power supply comprises UPS member controllers (12 and 13) and a UPS group controller (11) which are connected in a network (2) to control the operating status of the load devices (3) of the uninterruptible power supply (1). The UPS group controller (11) and the UPS member controllers (12 and 13) execute data communication according to a predetermined communication protocol (Internet Protocol or the like) through the network (2), and these controllers transmit/receive data in which specific identification information issued for each of the UPS member controllers (12 and 13) is added to control data as communication data in the data communication according to the predetermined communication protocol.

Abstract: 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 means 49 of uninterruptible power supplies 2 and 3 communicate with a load device 4 to which they themselves feed power, via a network 5. UPS storage means 47 stores a waiting time until the load device 4 starts shutdown after it is notified of detection of power abnormality of an AC power supply 6. Notification means 48 causes the communication means 49 to provide notification of a remaining time until start of shutdown, in a time period until a time period corresponding to the waiting time (67) stored in the UPS storage means 47 elapses after power abnormality of the AC power source 6 is detected.

Abstract: Each of connection data 11, . . . , or 15, of the downstream side of a socket 1, . . . , or 5 or a panel board 6, 7, or 8 in a power supply direction, is generated in a tap 16, a UPS 25 and 35, or a terminal 24 or 34, and each of the connection data is transmitted to a electrical system wiring diagram generating terminal 36. Then, a wiring diagram is generated, based on connecting information 91 of the upstream side, which is registered in the generating terminal 36, and the plural connection data of the downstream sides.

Abstract: 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.
