Input voltage is out of range, a phase is missing, or internal DC bus overvoltage has occurred.

In ECO Mode, the system prioritizes energy savings. Under normal conditions, the load is powered by the more efficient Bypass Mains. The UPS continuously monitors this source, and if the bypass voltage or frequency falls outside of specified parameters, the system instantly and seamlessly transfers the load to the inverter, providing full protection.
