Hey Sean,
I just said, I would avoid 110 V spindles (if stronger than 0.75 kW) and I linked to the exact explanations why, but rather choose one for 240 V. That’s all! 
By the way, Onefinity does not recommmend ANY spindle or VFD. They always clearly state that it’s your risk. And if they would recommend to attach a HY02D211B 110 V 2.2 kW VFD to a circuit not sufficiently dimensionated, they would be liable for recommending to violate the safety regulations in your country. So I am very sure they don’t. As the input current and power draw is willingly omitted both in the VFD manual and on the nameplate, you can only ask someone who knows how a VFD internally works an how you can calculate these ratings, and that gives that a 30 A circuit as usual in a domestic 120 V context is clearly not enough. However with the same model in the 200 V class, you would be good with 24 A and a 30 A fuse.
Really late now
PS: Regarding the fact that many people simply don’t know what a 110 V VFD for 2.2 kW motor can draw because many people never put a mechanical load on their spindle that would cause any issue with the power draw even on too weak circuit, the other day I posted this test to drive your spindle to its limits. It’s fun but it can show how easy it is to get to the limit.
