Necro thread bump. Just wanted to point out that it’s not just the divider that uses a reversed wiring color scheme. Inside the control cabinet the positive DC wires from the power supply are black and negative are white. It’s a catastrophe waiting to happen if someone goes to troubleshoot their machine with conventional wiring colors being red positive, black negative for DC. I mean, if you’re going to use white and black, at least still use black for negative.
Just a thought I’m contemplating as I prepare to install a replacement power supply for the DOA one that came in my controller. An easy task, made tiniest bit less easy because I have to remember to wire it “backwards” once it gets here.
