The devices arrived well packed, unfortunately without a manual. In front of me I had an aluminum box with 4 cables, two shorter, two longer. Which cables are INPUT and which are OUTPUT could not be seen. After unscrewing the case and removing the platibe it was easy to see that red/black was the voltage input, blue/yellow the voltage output. After connecting the cables accordingly, the device worked perfectly. Translated with www.DeepL.com/Translator (free version)
