2.6.5 Auto restart mode
When enabled, which is the default setting, auto restart mode automatically restarts the UPS after a shutdown that resulted
from depleted batteries after an extended power outage. A built-in 10 seconds delay after utility power is restored allows other
equipment to start first and stabilize before the UPS restarts.
2.6.6 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 98.7% 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 shutdown the bypass.
