PROBLEM TO BE SOLVED: To provide an uninterruptible power supply unit for facilitating the maintenance inspection operation of a secondary battery and the installation operation of the uninterruptible power supply unit. SOLUTION: An uninterruptible power supply unit(UPS) 1, compared with a conventional example uses a case 2 being composed of an external case part 3, where a power conversion part 8 is mounted and at the same time, accommodation space 39 for accommodating a secondary buttery part is formed inside, and a secondary battery case part 4 in which the secondary battery part is mounted. In the external case part 3, an upper-front surface cover 31 and a lower-front cover 33 are mounted onto the front surface, a side-surface cover 34 with a hole 35 for fixing the secondary battery case part 4 to the external case body 3 is mounted on both the side surfaces, and an installation tool 36 is mounted at four corners of a bottom part. The secondary battery case part 4 is formed into a shape and dimensions in a state where the secondary battery case part 4 can be accommodated in the accommodation space 39 is provided in the external case part 3, while a secondary battery unit 6 is mounted, and a wheel 41 is fitted to each of the four corners of the bottom part. |
