Diagnostic micromaster 440 question

Papadoc Posts: 1 Rating: (0)	I have a micromaster 440 15hp drive that is 380v-480v. That we are about to ship to a job as replacements. I would like to pre-commission the drive to make the start up a little faster as this is a high profile project. Can I attach 120v to the L-N terminal and boot the drive to input settings? I have done this previously with lower voltage drives and it doesnt seem to be working with the drives I have now. Thanks
