Abstract: A method is for connecting a capacitive load assembly to a DC grid. The load assembly is connectable to a supply potential of the DC grid by a control unit via a controllable switch element. The controllable switch element is periodically activated and deactivated by the control unit. The level of the current pulses flowing through the controllable switch element during the respective activation phase of the controllable switch element is detected by means of a current measuring device. The development of the level of at least two current pulses immediately following one another over time is evaluated by the control unit. The controllable switch element is additionally periodically activated and deactivated by the control unit if a specified change in the development of the level of the at least two current pulses immediately following one another over time is ascertained.

Abstract: Methods and systems for device maintenance are described herein. Objects, such as pills, tablets, capsules, etc., may build an electrostatic charge as they pass through a dispensing device.

The maintenance procedure may allow the objects to pass through various components of the dispensing device more freely.
