An electrically driveable vehicle, in particular a rail vehicle, includes an intermediate DC circuit, an in-vehicle, three-phase on-board electrical system fed by the intermediate DC circuit, at least one drive motor fed by a converter, and at least one coolant pump for pumping a coolant that cools the converter. In addition to the in-vehicle three-phase on-board electrical system, the vehicle also has a second on-board electrical system. The at least one coolant pump is connected to the second on-board electrical system.

The invention relates to a vehicle for transporting a biological sample, the vehicle being movable on a circuit, the circuit comprising: —an input path, a first output path and a second output path, —a turn-off enabling the vehicle travelling on the input path to be redirected to the first output path or the second output path, —a first guide path extending along the input path, the turn-off and the first output path, —a guide device which can be configured in: —a first configuration in which the guide device cooperates with the first guide path so as to direct the vehicle to the first output path when the vehicle passes through the turn-off, —a second configuration in which the guide device does not cooperate with the first guide path, enabling the vehicle to reach the second output path.

A method for operating a storage-and-retrieval unit (3) is specified, in which a rail line (1)/power-supply rail (6) is set to a hazard-operation voltage when a risk posed by the storage-and-retrieval unit (3) is detected. In the storage-and-retrieval unit (3) the level of the voltage applied to the rail line (1)/power-supply rail (6) is measured and a current path between the rail line (1)/power-supply rail (6) and a drive motor (5, 5a . . . 5c) of the storage-and-retrieval unit (3) disconnected when the voltage measured is below a threshold value associated with a hazardous situation or emergency. Furthermore, a storage-and-retrieval unit (3) as well as an automated rack storage system for performing the proposed method is specified.

A method and an arrangement for operating a storage and retrieval unit (3) are specified. A rail line (1) respectively a power supply rail (6) for the storage and retrieval unit (3) is set to a risk mode voltage, the rectified value/effective value of which lies below a minimum rectified value/minimum effective value necessary to move the storage and retrieval unit (3) but above zero, if a risk posed by the storage and retrieval unit (3) is detected. Alternatively or in addition, the voltage applied to the rail line (1)/power supply rail (6) can also be investigated in the storage and retrieval unit (3) for modulated change signals. The applied voltage is passed on to a traction motor (5) of the storage and retrieval unit (3) only when it has been established that the normal operation-traction voltage and not the risk mode voltage has been applied to the rail line (1)/power supply rail (6).
