Thanks again Tan! Sorry, I guess I don’t understand what a center tap is. I’ll wire the green pair as you say.

There is no green/yellow wire on this PT. There’s a green pair, red pair, yellow pair, black pair, and a red/yellow. I on the book layout, it shows the green/yellow in parentheses “(green/yellow)”. I assume that means that a green/yellow may or may not be there, correct? I just connect the red/yellow to ground and forget about the green/yellow.
