On one of the Centroid YouTube videos it say something like “Need to connect the commons of the power supplys.”
I have a Vfd, centroid power supply and this
Am I supposed to connect those 3?
Power supply commons

Re: Power supply commons
No. They are talking about the 0V (COM) outputs of the AC-to-DC switching power supplies.
What you have pictured is a transformer (AC-to-AC), which would only be used for contactor coils. It does not need a shared common with the DC supplies.

Re: Power supply commons
My Vfd and centroid power supply are AC to DC, should those commons be connected?
