Eco Mode-Single Ups - Vertiv Liebert EXS Installer/User Manual

1.5.5 Eco Mode—Single UPS
The UPS ships in Eco mode as the factory-default setting. Eco mode reduces power consumption and
provides UPS efficiency approaching 99% by powering the load via bypass if the bypass voltage is normal
or by powering the load via the inverter when the bypass voltage is outside the specified range.
NOTE: During Eco mode, if a bypass-failure or abnormal-bypass-voltage notification appears when the
output is not overloaded, the UPS will transfer to Normal Mode. However, if a notification showing
bypass failure or abnormal bypass voltage appears when the output is overloaded, the UPS will shut
down the bypass.
