Description for -SS2 single-phase output models
1) Generally, the output terminals U and W of the VFD connect to the phase cables of the
single-phase motor.
2) If the single-phase pump cannot be started, the two-phase control method must be used,
and the start-up and running capacitors (if any) of the motor must be removed. The figure
below shows the internal wiring of the common single-phase motor. In the figure, L1, L2, C1,
and C2 indicate the running winding, start-up winding, running capacitor, and start-up
capacitor. When the motor speed exceeds 75% of the rated speed, the start-up capacitor is
switched off.
