4.2.4 Bypass Mode
Upon connecting to Utility Input Power, the UPS is in Bypass Mode before UPS is turned on (if BYPASS enable
setting is Enabled), and Charger function will be active when Battery is connected.
After UPS has been turned on, if the UPS encounters abnormal situations (over-temperature, overload …, etc.),
the Static Transfer Switch (STS) will perform as a transference of the load from the Inverter to the Bypass source
with no interruption. If the transference is caused by a recoverable reason, the UPS will turn back to Line Mode
when abnormal situation has been solved.

4.2.5 ECO Mode
The ECO Mode can be enabled through the LCD control panel. In ECO mode, the load is diverted to Bypass when
the Bypass voltage and frequency are within the acceptable ranges. If the Bypass is out of range, the UPS will
transfer the power source of load from Bypass to Inverter. In order to shorten the transfer time, the rectifier and
inverter are working when the UPS is in ECO mode.
