The running capacitor is designed to act continuously in series with the starting coil (PSC connection), improving the starting and working torque and the electrical efficiency of the motor. In this wiring diagram, no relay is used and is applied in self-equalizing systems due to the normal starting torque.
Note: In case of replacement of capacitors, the same specifications of the original capacitors must be followed, that is, the capacitance (microfarad-mF) and insulation voltage (VAC).
