Hitachi four pole capacitor

To complicate it even further, the unit also came with the red 5 pole connector, which fits snuggly into my wall socket.

Could you guys help me think for a bit? I have some trouble finding the right transformers for my cause. I picked up a variac, but figured this would probably not work since it is not isolated, thus the N is not floating. Another small step down transformer that I have has the same issue. Will a isolation transformer in front of this solve this, or do I need to get a isolated step down transformer?
