Abstract
A method and an arrangement for operating a storage and retrieval unit () are specified. A rail line () respectively a power supply rail () for the storage and retrieval unit () 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 () but above zero, if a risk posed by the storage and retrieval unit () is detected. Alternatively or in addition, the voltage applied to the rail line ()/power supply rail () can also be investigated in the storage and retrieval unit () for modulated change signals. The applied voltage is passed on to a traction motor () of the storage and retrieval unit () 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 ()/power supply rail ().
