Method for adjusting operation parameters of an electrical device

A control apparatus provided to connect at least one electrical device to a power distribution system, wherein said control apparatus comprises:

• a human machine interface having human machine interface elements used to interact with the control apparatus, wherein the human machine interface elements is adapted to display and/or to adjust setting values of operation parameters of the connected electrical device, wherein the operation parameter setting of the connected electrical device is performed by a computer-implemented method for adjusting operation parameters of an electrical device connected via a control apparatus to a power distribution system comprising the steps of:
• checking automatically in response to a setting of an operation parameter of said electrical device input by a user by means of a human machine interface element of a human machine interface, HMI, of said control apparatus whether the respective device operation parameter is security-relevant for the operation of the connected electrical device, for the control apparatus itself and/or for the power distribution system;
• performing a user authentication of the user if the input operation parameter setting is found to be security-relevant;
• evaluating the operation parameter setting of the security-relevant operation parameter input by the successfully authenticated user to determine whether the input operation parameter setting is admissible;
• performing automatically an adjustment of the operation parameter of the connected electrical device if the evaluated operation parameter setting of the security-relevant operation parameter input by the authenticated user is determined to be admissible.
