[QUOTE="roys, post: 392208, member: 5044"] Nothing to worry about as others have said. When ever we connected up a motor a rotation check was always carried out and to us it was always 50 50 as to it being correct. A rotation check was always carried out, just the quickest on off you could get on the supply to say which way the motor would go. The exception to this would be any very sensitive piece of kit to wrong rotation where other safeguards would have to be put in place such as de-coupling the motor. As a side piece of info and as a general rule only so not guaranteed: For a brand new motor connecting it up L1L2L3 to UVW the motor will go counter clockwise when looking from motor cooling fan. Handy when connecting up banks of new motors on a new contract. [/QUOTE]
