Hardinge HLV rectifier swap

Hi, I'm trying to swap the selenium rectifier on my HLV for a silicon bridge type (just as as a precaution, it's not blown yet). I'm going crazy trying to work out which wires go where! The wires all come from the long terminal block on the left (pic 4) am I right in thinking that the AC 1&4 terminals (green and blue) go to the right hand terminals of the bridge, as pictured and the DC 1&2 go to the left two terminals of the bridge? Sorry if that's unclear, I just want to check before I start cutting wires!
