Emerson Liebert PSA Line-Interactive UPS 500-1500VA User Manual

When Liebert MultiLink detects a UPS Operating On Battery event, the following occurs:
1. A UPS Alert is displayed.

2. If the Command action (available in Liebert MultiLink Advanced only) is enabled:

• A timer starts that may lead to executing a command that the user or System Administrator 

has written to perform site-specific operations for applications that have command-line 

options.

• If this timer expires—the duration specified during configuration—the script is executed.
• To cancel the Command action manually, open the MultiLink Viewer, select the Event 

Configuration tab and remove the check mark (✔) from the Enable Command Action box. 

Click on MultiLink, then on Save.

3. If the Shutdown action is enabled:

• A shutdown timer begins when UPS Operating On Battery occurs. The timer’s duration is 

specified during configuration.

• If this timer expires before the canceling event UPS Output Returned From Battery 

occurs, the operating system is shut down.

• Liebert MultiLink notifies the user that a shutdown is impending.
• When two minutes remain on the shutdown timer, the MultiLink Countdown to 

Shutdown box opens.

• Clicking on Cancel Shutdown overrides the configuration 

settings and prevents the operating system from being shut 

down. A dialog box asks for confirmation before the shutdown 

is canceled.

• Clicking on the Pause Shutdown button suspends the 

shutdown process, including the timer. A dialog box confirms 

that the shutdown is paused and offers the options of canceling 

the shutdown or resuming the countdown toward an orderly 

shutdown of the operating system.
