Customer with a new soft start on a 75 hp well. POCO normally requires PFC on larger motors. From what I have read these should be installed on the line side of the SS, a min distance away and brought on line after it has switched into bypass. Question is how long should I hold the PFC offline to allow for discharge in case of multiple starts for whatever reason. Eatons state theirs discharge to less than 50v in one minute. 67 seconds close enough, or better with 5 minutes?
