Well, life got in the way, but I finally got the mill in position and made the wiring changes as directed. BUT, I get a -UU error, which the manual says is undervoltage. I put a meter between the R and S terminals and I see 248V. I also get 248V between the S and T terminals. Of course, since the R and T are shorted together, I don't see any voltage between them. Any ideas? TIA!
