    When UPS has no separate Bypass mains input, Bypass line is also fed from the mains input. Thus, if such a device is in question, mains input shall be comprehended when the Bypass mains input is referred in the following sections of the manual. UPS behavior at the start-up is different from the usual operation.

  • Page 15: Normal Mode

    3.2 Normal Mode Energy is drawn from the mains input. Loads are fed via the Rectifier and the Inverter. The AC voltage at the input is converted to a DC voltage by the Rectifier. The Inverter converts this DC voltage to an AC voltage with a stable sinusoidal waveform, amplitude and frequency.
