What is everyone's thought on vfd bypass contactor setup? My application is blower pulling air through a pipe and set of critical flow venturies. The vfd will be for energy savings, etc. I'm thinking that for the hardware cost of 3 contactors, etc that having dol bypass to keep running in the event of vfd failure is a good idea. This is for a 100HP motor.
