I bought a huanyang 220v vfd, I don't have 220v-240v plugs in my house so I bought a step up transformer 5000w, it appears that the step up transformer outputs are for european plugs that have one 220v live wire and a neutral, how do I wire that up to the vfd R S T terminals? Do I just plug the hot line into one of those or jump the 220v from R to T or R to S? I don't want to burn up my vfd. Also my step up transformer input seems to be wired up differently than the one in the picture from automation technologies, will that make a difference since it's only 110v. Thanks

You connect the Hot ( live ) wire to the R terminal the Neutral to the S terminal and the Ground ( Earth ) to the Ground ( Earth ) terminal

Make sure you set the Parameters in the VFD Drive correct to suit the Spindle you have, before you power up the spindle or you will damage it

Fortunately according to the spec, it seems that the transformer is a Auto-transformer type, rather than the typical isolated version.
Otherwise you would have had to re-establish the Neutral and Earth ground conductor(s).
