The common wire terminal is designated, according to the equipment, as SC, SG, G, GND, ground or reference. On the Wiren Board controllers, this terminal is designated as GND. When connecting to an isolated port, you need to connect to the isolated ground of the port ("GND iso"terminals). | The common wire terminal is designated, according to the equipment, as SC, SG, G, GND, ground or reference.
