Well that is a lousy website. I could not find your model number, but did find one 3 phase unit, and they state a ungrounded neutral.
I cannot imagine why. And most systems across the globe use a grounded neutral, so I would be looking for another unit that would match my typical system rather that spend money to buy their unit AND spend more money to change my system to meet their specs.
As far as using a transformer for your application, this is a pure resistive load, and harmonics's will not be an issue.
Have you spoken to their engineering dept, to learn why they insist on an ungrounded neutral? I would be very curious.
