The UPS may be programmed to “System Auto Start Mode after EOD”. The system
starts after a delay time when the AC mains recovers. The mode and the delay time
are programmed by the commissioning engineer.
2.3.7 Frequency Converter Mode
By setting the UPS to Frequency Converter mode, the UPS could present a stable
output of fixed frequency (50 or 60Hz), and the bypass static switch is not available.
