So, I'm suppose to put a wire into the holes where the screws are and then screw the screw back into the hole while the wire is still in there to use that terminal? I could somehow touch the wire to the screw too such as soldering, right?
No, the wire end goes in the opening, the screw on the top ( 90 degrees from the wire inserted) gets turned to lock down the wire.
