The thing I was wondering is, do I need a power source again because I connected the power PS 60W module in the left part? More precisely, I wonder. What is the difference between PS and PM? If I connect PS to the system, do I need power source again? Can I use an external power supply and remove the PS? I get an error like this: "One article of the device is not connected to a power supply yet." Thank you and have nice work. Attachment Screenshot_2.png (323 Downloads)

Best regards, Wizard
