Star delta connected as above. The phases are in correct rotation (have a phase rotation relay in control circuit). Motor is running in reverse, but I can't for the life of me remember how to reverse the motor at the motor terminals. I can't just swap the MCCB feed so how should I alter the wiring at the terms to make the above work?
be careful - that works with a motor wired with fixed links, but if you exchange the L1 and L2 to the ‘1’ ends of a pair of windings, but the supplies to the ‘2’ ends of the of the same windings are not also swapped, that will reverse it for starting in star, but as the starter is supplying both ends separately, you can have a situation where once up to speed the right way, and switched to the delta connection it may then try to reverse and go round the wrong way - which is likely to be very impressive/expensive.
Of course if the starter is supplied from a point after the L1- L2 switch, then you do not need a second swop…
