Connecting device for electrically connecting a three-phase motor

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 parallelepipedal, 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
• the coupling module or each of the 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.
