Faema E97N Espresso machine 230 -> 400V conversion

Hey! I have just bougt a Faema E97N espresso machine from 2002. Currently its wired for 230V 3 phase from the previous owner, but it needs to be converted to 400V 3 phase with Neutral. The label says "3PNE AC 220-240/380-415V" so i belive it is possible to rewire it but cant find any information about it, does anybody know a solution to this? I live in Norway
