I am trying to wire up this Kaeser compressor model SK26. It is a 26HP motor, but it has a 12 wire system for star delta configuration. I haven't touched star delta in a long time, and when I did I had help. I don't want to mess this up so I asked a local electrician. He took a look at it and started talking about double "wye" and double "delta", which didn't make much sense to me. He then told me he wasn't super knowledgeable with this configuration. I asked him to just leave it go and I would do some searching around. Originally the compressor was setup for 460v three phase, but I am trying to wire it for a 230v three phase unit. I had started to move the connector bars before the electrician showed up. I wanted to know if anyone on here would be able to explain how this connection goes. I have only ever seen star delta setups with a main contactor and two relays for the delta-star sides. I really appreciate it any help.View attachment 272911
