Note
There is a short interruption time (less than 10ms) when transfer from ECO mode to battery mode,
it must be sure that the interruption has no effect on loads.
2.3.6 Auto-restart Mode
The battery may become exhausted following an extended AC mains failure. The
inverter shuts down when the battery reaches the End of Discharge Voltage (EOD). 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.
