Do i get the Wiring of the Power Supply right?:
Outlet ------ Cable --------> Relay Board ---------Cable --------> Printer Power Supply (My Printer does not have a switch)
Does it matter in which way I connect the Cables to the Relay?
The Screw Terminal is build like that I believe : [Normally Open] [Common Ground] [Normally Closed]
Is the Left Cable going to your Power Supply or the Outlet?
Looking forward for a reply.
