  • Page 16: Auto Restart Mode

    When enabled, which is the default setting, Auto Restart mode automatically re-starts the UPS after a shut-down that resulted from depleted batteries after an extended power outage. A built-in 10-second delay after utility power is restored allows other equipment to start first and stabilize before the UPS restarts. Vertiv | Liebert® EXS™ Installer/User Guide...

  • Page 17: Eco Mode-Single Ups

    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.
