2. 220 V device to 230/240 V mains: 

Device can be operated with 240 V (50 Hz).
In former times a mains voltage of 220V was valid in Germany. 
In the EU (and now also in Germany), currently a mains voltage of 230/240 V (50 Hz). 
In 2009, the tolerance threshold will be further increased. 
In extreme cases up to 250 V mains voltage can be present.
This can lead to problems during operation and to a reduction in service life.
Due to the increased mains voltage of 5% (230 V) or 9% (240 V), the device may heat up more.
increased heating of the device is to be expected. 

It is advisable to switch the device to 240 V.
