Installation documentation could be better. When discussing how to wire it up, it gives contradicting information. Text - White wire (live), Black wire (neutral) but the diagram shows White wire (neutral), Black wire (live). Fortunately, the Green wire is ground in both cases. Maybe the polarity doesn't matter since it is an AC product but nice to state best way only. They could also include a 3 prong plug for those wanting to connect the electricity that way.
