* Note: Power factor correction capacitors (PFCs) can reduce a facility’s kVAR charges in some
cases. Determining the need for, and location of, PFCs should be performed by a qualified
engineer (from your utility company or a power quality engineering firm). PFCs cannot be
located between the SR55 and the motor.
