    Are you planning to use the digital outputs 0-3? If you are, then you need to connect 24V to the + and- as shown. If you are not using them, you don't need to connect power to those pins. As I remember, you use one of the relay outputs to switch the VFD and they don't need this extra PSU connection. You could use the digital outputs for things like switching coolant on/off, although personally I don't bother and use a manual switch.
    Brilliant thanks! Got all the UTP connections in now:
