Use a screwdriver to loosen the screws of the wiring terminal block and use ring-
type terminals to secure L1 (line), N1 (neutral) and G (ground) wires into the terminal
block and lock them. Since it is single input, each power supply unit should be each

terminals and use another N1 (neutral) wire to connect N1 and N2 terminals.
