Abstract: An input connector assembly, which is for detecting residual current and adapted for connecting power sources to electric equipment of electric vehicles, includes a wire terminal block, lock and release mechanisms, a residual current sensor, and a support holder. The wire terminal block has wire terminals for receiving electrical wires. The lock and release mechanisms are connected to the wire terminal block for fixing electrical wires to conductors in the wire terminals. The residual current sensor is adapted to be mounted to a flat surface. The support holder is designed to be placed above the residual current sensor and to be connected to the flat surface. The support holder is further adapted for supporting the wire terminal block in a position above the residual current sensor. Conducting connection pins run from the conductors in the wire terminals through openings in the residual current sensor to the flat surface.

Abstract: A charging station, which is for charging an electric vehicle, includes an outer housing containing controller and power electronics mounted to at least one printed circuit board; an interface enabling connection of the charging station to the electric vehicle; and at least one light source connected to the at least one printed circuit board. The interface is a connector made of a translucent or semi-translucent material in at least an area of the connector directed at the light source.

Abstract: A robot controller for an industrial robot is described. The robot controller is a portable controller of the TPU Teach Pendant Unit type and comprises control means for moving a robot in three or more degrees of freedom. The TPU comprises a visual display and selection means associated with programming or controlling a robot. In other aspects of the invention a system comprising a robot and a control unit and the TPU are described. A computer program of the TPU for carrying out the method is also provided.
