I’ve just come across a motor with 12 terminal and I have doubts about its connection. I’m trying to connect it in delta but the diagram is quite confusing. Any ideas please. The old pump motor on this unit had the normal connection type.
thanks

 

Obviously choices of two star and one Delta opions for connecting, is there no other explanation in the terminal box?
What make model of motor?

 

The label is straight forward, where’s the confusion?
