Prior to continuing the assembly, the wiring must be completed and the SKR 2 / Octopus 1.1 motherboard needs to be prepared for RatOS

Mains electricity can cause serious harm or kill you. If you are not experienced working with mains electricity, consult a qualified electrician

The 24V power supply may need to be set to your local mains electricity voltage

There is a label on the power supply showing the location of the switch, and the position it must be set to depending on your whether your mains voltage is ~115V or ~230V

A full wiring diagram is provided in the electronics section of the V-Minion product site

After successfully wiring your electronics, you may proceed with the Preparing your Control Board section of the RatOS guide

Once the wiring is complete, and the SKR 2 / Octopus 1.1 is ready, proceed to the next step
