The grounding function unit is selectable to a manual operation state by moving the first moving control element to the first manual operation position, and the isolation function unit function unit is selectable to a manual operation state by moving the second moving control element to the second manual operation position. When the manual operation state is selected for one of the grounding and isolation function units, selection of the other of the grounding and isolation functional units to the manual operation state is blocked by a respective one of the first and second moving control elements.
