[QUOTE="Barx, post: 419125, member: 121"] Wish I could help you there, but I don't think I will be going back now as all is up and running. The bottom section is just for connecting. So, on left was a set of Din connectors for 3ph supply. Then on right was 18 x Din connections for CT's. In top, CT's were connected to Current Summation transformers with the output going to the front panel. There was some other bits in there but I cannot remember, sorry. The contactor panel was just that. As seen below. This panel could switch 6 x inverters. We also had a very similar (but bigger) panel that was for Fire Alarm control and that cut out all 13 inverters. I enjoyed wiring them up ;) [ATTACH]6862._xfImport[/ATTACH] [/QUOTE]
