  • Page 17: Command For Power Factor Correction

    Control for a SSW7000 The SSW7000 can control the motor power factor correction (PFC) capacitor bank directly through a digital output (DO1, DO2 or DO3) programmed for “PFC Control”. The digital output will then be activated after the motor starts and after the bypass contactor closes, thus preventing the capacitor bank from being activated with the motor turned off or during the motor start or stop.
  • Page 18 Figure 3.7: Parallel connections between "n" SSW7000C In order to automatically control the motor power factor correction (PFC) capacitor banks for multiple SSW7000, a digital input (DI1, DI2, DI3, DI4, DI5 or DI6) must be set to “PFC Lock”, a digital output (DO1, DO2 or DO3) must be set to “PFC Control”, and another digital output must be set to “PFC Lock”.

  • Page 19: Ssw7000 Identification Label

    The start of multiple SSW7000 is done sequentially and/or simultaneously. For the simultaneous start condition of two or more SSW7000, the PFC capacitor banks will be enabled at the same time after the start of the last motor. As described by IEC 60871-1, the peak value of the capacitor bank inrush current must not exceed 100 times the value of the rated current.
