From Wiki...
Since the early 1990s grounded outlets have been required in all new electric installations in Denmark. Older outlets need not be grounded, but all outlets, including old installations, must be protected by
ground-fault interrupters (HFI or HPFI in Danish) by 1 July 2008.
I guess this explains it. You cannot not have HFI, and this one sits before the electricity enters your house/apartment.
Though you still need ground on the socket if you install a dishwasher. But I'm strongly considering it.
We installed it at work (digital mixers and guitar amps) so I'm not unfamiliar with the whole thing
But thanks for the concern.
And the Audya hasen't had a restart in 2 days, so there's that.
