Active ECO Mode

All Liebert GXT4 models can operate in Active ECO Mode. In this mode, the connected equipment is
powered through the bypass path to increase efficiency, reducing the electrical costs.
Active ECO mode keeps the rectifier and inverter operating, allowing the inverter to remain synchronized
to bypass. This synchronization allows the transfer of the connected equipment to UPS inverter power
almost seamlessly if bypass power falls outside the user-set limits. Once bypass power returns within the
acceptable parameters, the UPS will return to Active ECO Mode operation.
The default setting is Active ECO Mode Off.
