Questions about Heidelberg Home Eco De version 5m

What's the difference between the DE version and the EU version? Which do you prefer for Switzerland?

Did I read correctly that this charging station has a charging capacity of 7.3 kW with a connection of 1 x 400 volts and 16 amps?

Hello, I would like to know if this terminal can be installed in Switzerland? I saw a comment saying that it was the German version and that it was not compatible in Switzerland.

Does this product have a restriction such as access only with an RFID card? Does this product have an app to control the charging times?

How can I prevent someone else from charging at the charging station?
