PROBLEM TO BE SOLVED: To curtail the manufacturing-time man-hours of a power control board. SOLUTION: A control unit 35 provided in the main circuit unit of a power controller has an operation changeover switch 50 in a frame 38 along with an operation indicating lamp 48. This control unit 36 is fitted inside the cabinet of the power control board. If the front door of the cabinet is opened, manipulation of the changeover switch 50 becomes feasible along with indication confirmation of the indicating lamp 48. Consequently, fitting of the operation indicating lamp and operation changeover switch to the front door of the cabinet becomes unnecessary any longer, and omission of working of the front door and fitting work of the operation indicating lamp and operation changeover switch becomes feasible. |
