What RJ said.
In the US the second 'hot' would be protected by the breaker. 220 single phase breakers protect both poles.
Connect the PE (green) to the Earth connection on your outlet/box. it doesn't carry functional current - it is your protection if something comes loose or fails in such a way that the chassis of the mill becomes 'hot'.
A 240 V single-phase breaker is normally two poles in the US -- meaning it would protect both legs. Why would they incorporate a fuse in only one leg in a 240V appliance expecting to be wired across two legs?
