Hi,
Connect like this:

1. A0  & C1 to line

2. B0 & A1 to line

3. C0 and B1 to line.

No neutral connection.
Basically take the 3  neutral / starpoint wires on terminal 4 and move them to the relevent terminal.

Robert.

Look up steinmetz connection. You have got the instructions for converting from star to delta. This will involve a capacitor. Good luck. Noel.

Wade, the need for a capacitor is not for starting as in single phase but to give phase shift to create a false Phase. Noel.

For 3 phase supply on a 3 phase motor,  I have never seen a capacitor used.

I suspect some folk are thinking you’re wanting to run a 415v three phase motor on 220v single phase, and providing capacitor instructions for that. (about 4 microfarad for that on this motor)

Yes, if you’re running 220v 3 phase, just change the wiring from star to delta, but ensure your three windings all face in the correct direction on the pump motor, or it will run unevenly as one winding will be opposing the other two.

Reversing the motor necessitates reversing any pair of phase windings on the supply side of the connection strip, not the motor side. i.e. Reverse supply A-B not winding U1-2

Just a reminder for anyone new to 3 phase that if it goes in reverse to what you want all you have to do is swap over two of the input wires.
On a lot of older motors the star point where all 3 are joined is buried in the middle somewhere. Lots of people say they just poked around and found it but if you or I tried that SOD’s law says the old insulation would disintegrate and short out ruining the motor.

Seriously!

How old does motor winding have to be before it disintegrates, 50 years or even 80 year old wiring and insulation should be usable if the modification is carried out with care, SODs law might make its appearance in a tiny percentage of cases but it would not stop me trying to convert an old motor.

P.S. I was just about to post this when I realised I would just be adding yet more noise to this thread.

I’m not sure whether the OP’s original question has been answered, but certainly some of the replies seem unrelated (as is this one of mine!). It may be that the OP did not give enough information or phrase the question clearly but diversions into Steinmetz and capacitor startings seem a bit irrelevant.

Actually after reading most of the thread again and noting that the motor is wired to run on 440V three phase, my suggestion would be to connect to the three phase and just run it. As a coolant pump it is not heavily loaded so work just as it is.
