5.4   Operating modes

The Eaton 9PX front panel indicates the UPS status through the UPS indicators, see page

11.

Online mode 

During Online mode, the 

 indicator illuminates solid and the UPS is powered from the utility.  

The UPS monitors and charges the batteries as needed and provides filtered power protection to your 

equipment. Optional High Efficiency and Energy Saving settings minimize heat contribution to the rack 

environment. See user settings on

page 13.

Battery mode 

When the UPS is operating during a power outage, the alarm beeps once every ten seconds and the 

indicator illuminates solid. The necessary energy is provided by the battery.
When the utility power returns, the UPS transfers to Online mode operation while the battery recharges.
If battery capacity becomes low while on Battery mode, the audible alarm beeps once every 3 seconds.  

This warning is approximate, and the actual time to shutdown may vary significantly.

Shutdown all applications on the connected equipment because automatic UPS shutdown is imminent.
When utility power is restored after the UPS shuts down, the UPS automatically restarts.
