Depends on the unit, and how truly isolated everything is. I know some models which don't tie either polarity so the isolation isn't necessarily. I know of others which won't even start without being solidly grounded on both the ac and DC sides.
>From a practical perspective, if you don't tie either the ac earth ground or the output to ground, and isolate the chassis, I'd expect the output to be able to be used in either polarity. However, there are numerous unsafe conditions which may be created by this, expecially if the negative output terminal gets grounded.
