The blocking action of a 3 phase bridge should cause no conduction from live to neutral if a neutral was so connected to a phase input.
My point about the ground was that you violate the code if you use the neutral as a ground.
The system neutral should be only grounded at source, and this applies to local supplies where a local neutral is set up.
The only reason I mentioned the link was to quote the manual for David's information.
It probabally does not matter what pair you use, as the input usually enters to a 3 phase bridge, the alternative is where there is a 1 phase ac control source connected to a particular pair.
