Please can you guide me the correct wiring for the SMC-3 Delta with 12 leads Motor on delta run. We received an SMC-3 soft starter with six output, i got confused on power wiring.

How many wires are you running from the starter to the motor? If it’s just three as in that drawing, then just ignore the other three terminals on the starter. Those are only there for when people (usually OEMs who will spend as little as possible) want to buy a starter that is 58% of the motor rating and take advantage of the 12 leads in the motor by running 6 conductors and separate the windings, placing the soft starter in SERIES with the windings instead of in parallel with them. It adds risk of failure and makes replacement more difficult, so it never benefits an end user.
@ SaltGeorge thank you for the wiring you have provided.
@ Sir Jraef, the existing one is six wire going to the motor from the starter, its wye delta connection. I would go for the 3 wires which is Line Connection.
