Patent ID: 8395290

Claim:
A connecting device for electrically connecting a three-phase motor having at least three windings to a three-phase network, the connecting device being substantially parallelepiped, comprising a mains connection unit for connecting the phase lines of the three-phase network, a motor connection unit for connecting the six winding ends of the three-phase motor, an exchangeable coupling module, wherein the coupling module is arranged between the mains connection unit and the motor connection unit and contains contacts and wiring elements electrically connecting the six winding ends in a predefined manner to the three phase lines of the three-phase network, a first coupling module being provided which couples the three windings in a delta connection, and a second coupling module being provided which couples the three windings in a star connection, and one of the first and second coupling modules or each of the first and second coupling modules being adapted to be mounted so as to be rotated through 180° along a coupling direction to thus reverse the direction of rotation of the three-phase motor.
