Like Jonathan, I thought that the Huanyang VFDs were wired to support single- or three-phase operation as that's how they are described in the manual. I just picked two terminals on mine and it works fine. But if they've changed this, or some of the current crop of Chinese VFDs don't match the usual Huanyang spec, or some are just not wired internally in accordance with the manual, then that's well worth knowing.
