The device (10) has power electronics (14) for a drive motor (16), and a signal barrier (30) for disabling transmission of control signals for the power electronics, where the signal barrier is designed as a separate circuit device for the lift control device. Signal transmission elements (34, 36, 38, 40, 52, 54) are connected in series for transmitting the control signals. The signal transmission elements are coupled with a voltage source (62) via a voltage supply circuit (56), where the coupling between the voltage source and the voltage supply circuit is deactivatable. |
