A frequency converter comprises energy transfer means capable of wireless inductive power transfer to a wireless terminal device placed to an inductive charging position of the frequency converter. In response to recognising that the terminal device is placed to the charging position, an identification procedure is carried out between the frequency converter and the terminal device via a wireless connection established between the frequency converter and the terminal device. If based on the identification procedure it is determined that the terminal device is an authorized terminal device, the method comprises displaying, on a display of the frequency converter, a user interface of the frequency converter, such that the frequency converter is controllable by a user by means of interactive elements displayed on the user interface. |
