Hello, I’m trying to set up my 6040 and I’m having problems with the VFD. I’m hoping you can help. I don’t have a manual and I have looked at some videos but can’t figure it out. I have figured out the power input wires(blue/brown/yellow greenish) but know I have the spindle wires to connect up. Some videos say I need to earth it (which I don’t know how) and others just connect up the three wires(UVW) I’m a moron at electrics. Any guidance would be greatly appreciated. Thank you
