    Supermax 821200 1.5HP dust collector switch wiring question

    Stupidly, I didn't take a photo of the wiring inside my motor box before I rewired it for 220-volts. The switch works fine, but there's a built-in circuit breaker and I have a "leftover" wire and don't know where it goes. Can anybody with this machine please snap a photo or two of your wiring?

    Thanks for any help!

    No experience with the separator.
    If you post the schematic and the wire and components in question, I'm sure we can figure it out.

    All I really need is a photo to see what the wire in question used to be connected to. I don't have access to a schematic or I probably could've figured it out. Thanks for the suggestion, though.

    If you post a picture of what you have, we should be able to figure it out.

    Here's some pics of my setup currently wired for 220-volts. Dust collector powers up fine, but there are two wires not currently connected to anything. I assume they tie into the circuit breaker. Supermax also just sent me a wiring diagram, but I'm not great at reading these. Not even sure it's the right schematic as I don't have any "purple" wires.

    I can't read the schematic you posted, it's blurry.

    I added a sketch of how I would wire it.

    Put the 240V to the switch, black and white.
    Switch red and black on the load side of the switch.
    Connect the red (on load side of switch) to U2
    Connect the red (on load side of CB) to U1

    The way it's currently wired, the motor doesn't have thermal protection and there is always 1 phase (120V) present at the motor.
