摘要： PROBLEM TO BE SOLVED: To surely perform the confirmation of connection of a coupler by incorporating the primary and secondary power cables of a coupler and power equipment in connection confirmation positions, and performing the connection confirmation of the coupler directly. SOLUTION: After connection of a coupler 4, the first and second switches 10 and 11 connected to external cables 8 are closed at the same time. At this time, if the pens 4x and 4y of the coupler 4 are connected both, an electromagnetic relay 13 is excited. Moreover, any one of the pins 4x and 4y of the coupler 4 is not connected, the electromagnetic relay is not excited, so it is judged that the coupler 4 is not connected yet. Next, in the same way as above, the coupler 4 is connected, and the switches 10 and 12 are closed at the same time. At this time, if both the pins 4x and 4z of the coupler 4 are connected, the electromagnetic relay 13 is excited. Moreover, unless any one of the pins 4x and 4z is connected, the electromagnetic relay 13 is not excited, so it is judged that the coupler 4 is not connected yet.
