this is an english only forum. please provide your information in english and we may be able to help you but reading the drivers assist message, you need to raise the panto and close the connection.
In order to activate the train, insert the master key, and set the reverser to neutral. You can then press the yellow 'Electric' button and then press the blue 'Pan up' button to raise the pantograph. However, given that the Azuma is not under UK power, I would imagine that unless you have selected "Off The Rails" in scenario planner, it cannot operate under the European power.
