Abstract: An energy store includes a housing and bridge plug. In relation to the housing, the bridge plug is receivable by the housing in two orientations different from each other, e.g., in the same opening or configuration of openings.

Abstract: A method for producing, especially configuring, a system is provided, including a contact wire and an apparatus, and device for carrying out the method. The apparatus is able to be supplied with energy with the aid of the contact wire, and information is transmittable from and/or receivable by the apparatus via the contact wire. The contact wire has at least a first, second, fourth and fifth contact conductor that are connected to one respective connector element of the apparatus. The first and second contact conductors have one respective phase of the AC voltage supplying the apparatus. The fourth contact conductor is provided for transmitting information and the fifth contact conductor is provided for receiving information. One of the phases, thus especially the phase acting as signaling phase, is connected electrically to a first connector element, in particular, the first connector element is provided with a corresponding marking or identification when producing the apparatus.

Abstract: A system for transmitting power and data, particularly including a half-wave control, includes a control unit connected to grid phases, the system having a phase-failure detection device which has bistable multivibrators, especially bistable multivibrators assigned to a respective grid phase. Each bistable multivibrator has an input for setting and an input for resetting, one of the inputs being connected to a digitizing device for digitizing the positive half-waves of a respective grid phase, the other of the inputs being connected to a digitizing device for digitizing the negative half-waves of a respective grid phase. The effective value of the output voltage of the bistable multivibrator is compared by a comparison device to a threshold value to detect a phase failure.
