Changing the UPS shutdown time when battery is low
Enter the "Low Battery" shutdown time in seconds. This is the amount of time that the UPS
will wait before shutting off the power supply when the battery level is low.
This prevents the UPS battery from becoming too discharged if the Windows UPS service is not
enabled and the UPS is therefore not turned off by the operating system.
If the UPS service is enabled, then the UPS will be turned off by the operating system when the
battery level is low, based on the Windows UPS service
Turn-off delay (see 10.4.7 "Changing
additional UPS settings"). The low battery shutdown time will then be ignored.
10.4.7 Changing additional UPS settings
1) Open the Control Center in the Control Panel .
2) Select UPS tab.
3) Click on Advanced under UPS settings . This opens the following dialog box:
Information:
• The low battery shutdown time must be set to at least 60 seconds, so that the
operating system has enough time to send the shutdown command to the
UPS when the battery level is low (normally occurs after approximately 30
seconds).
• The low battery shutdown time can only be set in UPS firmware version 1.10
and later. UPS firmware version 1.08 always uses a turn off delay time of 180
seconds. UPS firmware versions earlier than 1.08 do not shut down
automatically when the battery level is low.
