5.6 Economy mode

Economy mode is an energy saving mode. In this operating mode, UPS transfer loads to consume power from bypass power source when the bypass power source is normal and run the INVERTER operation to be the backup source when the bypass power source fails.

5.7 Sleep mode

Sleep mode is an energy saving mode. In this operating mode, UPS transfer loads to consume power from bypass power source and stop the INVERTER operation when UPS found no connected load or load consume power from the UPS is lower than no load condtion setting. During Sleep mode, If there are loads greater than set value, the INVERTER section will restart automatically and exit from sleep mode.

When UPS found no load and bypass power source fails, UPS will start INVERTER section and stand by to be the backup power source when there is load.
