In battery mode (not battery test state), when the battery voltage reaches
D.G. startup batt. volt.
or
Low battery voltage
, the UPS triggers D.G. startup signals.
In normal mode or bypass mode, if the mains is normal (the mains supplies power for 1 minute and
the D.G. runs for 15 minutes), the UPS triggers D.G. shutdown signals.
If the battery voltage is greater than
D.G. startup batt. volt.
, the UPS exits intelligent mode and
triggers D.G. shutdown signals. If the battery voltage is less than
D.G. startup batt. volt.
, a dialog
box is displayed, indicating potential risks. Tap
