接続できる状態となる。Connection / disconnection of the electric motor 1 and the external cable 4 is performed by attaching / detaching the fixed portion 31 and the movable portion 32 of the cable connector 3 mounted on the connection box 2 as described in the conventional example.
However, since the removal space of the movable part 32 is restricted by the protective cover 5, the protective cover 5 is first removed when the cable connector 3 is attached or detached.
When the protective cover 5 is removed as shown in FIG. 6, the signal S S having the logical value “0” indicating the removal state of the protective cover from the interlock signal generator 6 is inverted by the signal inversion device INV to obtain the logical value “ 1 "signal S R , power switch 7
“OFF” shutoff signal S With or without OFF , shutoff signal S
RS occurs, and the main power supply circuit 10 is shut off. Furthermore, the sixth
Since the signal S S (logical value “0”) indicating the removal state of the protective cover 5 continues to be generated from the interlock signal generator 6 during the attaching / detaching operation of the movable part 32 shown in the figure, the power switch 7 is mistakenly turned on. It is generated poured signal S ON Te main power supply circuit 1
0 is never connected. When the protective cover 5 is attached after the cable connector attachment / detachment work is completed, the interlock signal generator 6 generates a signal S S (logical value "1") indicating the state of attachment of the protective cover 5, and the power switch is turned on.
10 is turned on, power switch 7 turns on signal S ON
Is generated, the connection signal S SS is generated and the main power supply circuit 10 can be connected.
