Thanks
The power supply you linked to does not require an earth BUT the case or box that you mount it in will need to be earthed. If you are using this with stepper motors etc. Use screened cables like CY 4 core and connect all the screens at the control box end to a star point (ie one fixed point) and all other earths to that same point including the machine frame, which is then connected to your main earth.
If you are not happy with wiring 230V then ask for help from somebody that is. ..Clive
