Hi
Me again, I hope this isn't a stupid question. Is it necessary to have the input phase correct on the ac mains side of a vfd. The reason I asked is the mains plugs over here in Austria are not orientated, unlike the British mains plugs. Using the European plug if correct orientation is required i'm going to have to use some kind of marking. I don't want to blow up the hitachi vfd as it wasn't cheap.

Cheers

Andrew
