A method for operating a controllable electrical device connected by a data link to a control device for controlling the electrical device, includes using the electrical device to exchange electrical power with a connected electrical grid and using an environmental sensor for collecting environmental information. The control device transmits control signals to the electrical device over the data link. The electrical device assumes a first or a second operating state depending on the control signals transmitted. The electrical device exchanges energy with the electrical grid in the first operating state and the electrical device does not exchange energy with the electrical grid in the second operating state. Environmental information collected by the environmental sensor is transmitted over the data link to the control device only when the electrical device is in the second operating state. An assembly for carrying out the method is also provided.

A potential equalization system for a modular multi-level converter. The converter has a plurality of converter modules and each of the modules has a direct current source. The potential equalization system includes pole contacts, which are each electrically connected to one pole of a direct current source, and at least one electrically conductive contacting element, which can be moved between a first end position in which the contacting element is electrically isolated from the converter modules and a second end position in which the contacting element contacts pole contacts of different direct current sources and can be put on ground potential.
