Need help connecting to 240 volts

[Ali Lama]

Hello,

 i wonder if someone could help with the wiring of this power board supply that takes in 240 volts and DC as output.

As you can see it has (Ground, 230V, Common) as the three hook up and to the right of common is 4 hook up as the motor RPM. ( 1400, 1250, 1200, 1000)

Of the four wires in my circuit panel in my house  ( 2 black wires , 240 volts between them,wire A, and Wire B)

1 white wire, Wire C ( 120 volt with respect to the above two black wires.)

1 Bare copper  wire , wire D ( no voltage between it and the above three wires).

Which 3 of the above 4 wires ( A,B,C,D)  should be plugged in to the three hook up on the board.

See picture.

Thank you.

I will not try to answer this, just add some observation. The question seems to be more about the local conditions of the house than about the power board supply. Wiring standards will differ from country to country and there may be different local regulations.
