Nice, you'll want to hook up that earth terminal right away since you have live on both conductors now and the big capacitor in that VFD is going to mask any earth faults from your RCBO, so it's going to hurt a lot if the insulation in that fan isn't up to the job. In the future you would be better off using an actual 3 phase fan, it'll spin up pretty much instantly to whatever speed you set it to and will be much more power efficient.
This was in my recommended videos. They've got me figured out.

Lol, if overkill had a cousin. I was about to do something similar a few weeks ago.
Are there any settings on the VFD for the cooling fan? If there aren't, you could put a thermal switch in line with the fan, something like a ksd-01f.
@benlee4940 I don't see any reason why you couldn't add a thermal switch to the heatsink the switches it on once it reaches 40°
