PROBLEM TO BE SOLVED: To solve the following problem that may be encountered when upper and lower partitioning plates for forming functional unit compartments are replaced: it is necessary to pull not only a relevant functional unit but also a functional unit located above or blow the functional unit out of a switchboard and this has influence on the operation of the functional unit other than the relevant functional unit and it takes much time to replace the partitioning plates.SOLUTION: A switchboard is provided with: partitioning plates so attached as to partition the interior of a frame enclosure into multiple functional unit chambers; functional units housed in the functional unit chambers partitioned by the partitioning plates; guide rail members attached to the frame enclosure in positions corresponding to the functional unit chambers; and guide pieces that are attached to the functional unit chambers, engaged with the guide rail members, guided by the guide rail members, and used to attach/detach and hold the functional units. |
