Attention: The cable bridge connector is a push-pull connector. Ensure not to insert
it at an angle into the EU connector. The connector coupler has to be inserted before
the Pin-holder is pushed in. Otherwise the connectors might be damaged.
The cable bridge connector provides two notches, the EU
connector two noses.
