Hello guys and gals.
I have a powerflex 400 drive controlling a 100hp motor. Between the drive and motor I have a disconnect.
What would happen if this disconnect is off when the drive gets start bit?
What would happen if this disconnect is turned off while running?
Drive specialist is telling me I need aux contact on disconnect to let the drive know when off. He said it could damage drive underthese conditions.
This disconnect is required by code.
Can you explain to me why this contact is important?
