    Does anyone have photos of the internal wiring of KBAC-27D wired for the 240v usage? Every video on YouTube is guys running their VFD off of 110V.

    On the left side of the machine (for arguments sake let’s say I am using 10 gauge wire) 10-3 wiring hooks up the VFD to the motor, Black, Red, White, Ground...no problem that’s clear.

    Now on the power side. I have run 10-2 wire from where my grinder will be, receptacle/plug etc, over to where my panel will be with a 240v 20 amp breaker. I did this because it was my understanding because I was going to use 240v power the right side of the VFD L1 L2 would be both hot, Black and Red.

    When wiring it 110v L1 is hot Black and L2 is White neutral.

    Someone correct me, or put my mind at ease I have it right lol

    Cheers,

    Griff

    You need the two hots and one ground for the supply power. No neutral required.

    Make sure to set the jumper J1 to 230 V.
    Wire L1 and L2 from your hot 1 (black) and hot 2 (red). lastly a green wire to one of the ground screws.

    You should be good to go.

    If you are setting it up for 115 V, then J1 is set to 115 V and L1 is hot and L2 is neutral.

    I was going to say "Dan has got to be all over this". He's the guy I pester about wiring stuff. (i have some kind of psychological block about understanding wiring diagrams)
