2.2.2.5 ECO Mode

The economic control operation (ECO) mode is an economical working mode, which can be
configured on the LCD or web user interface (WebUI). In ECO mode, when the bypass input
is within the ECO voltage and frequency ranges and other ECO power supply conditions are
met, the UPS works in bypass mode and the inverter is in standby state. When the bypass
voltage is outside the ECO voltage range, the UPS transfers from bypass mode to normal
mode. In bypass mode or normal mode, the rectifier keeps working and charges batteries
using a charger. The ECO mode delivers a high efficiency.
