4. On the Shutdown Parameters window, enter the following parameters:

– UPS Low Battery Signal Time: This condition will occur if the battery is

very old and the UPS can supply power for a short period only (thus

immediate actions are required). It is the minimum number of minutes of

battery run time that the UPS needs to perform the essential tasks of a safe

system shutdown. Possible values are 2, 5, 7, and 10 minutes. We

recommend 10 minutes to get enough time for shutdown.

– UPS Turn Off Delay: This period of time begins at power loss. After this

interval, the UPS turns off its output power (independent of any shutdown

completion). If line voltage returns during this period, turnoff of output

power is canceled (again independent of any shutdown operations in

progress). Possible delay values are 20, 180, 300, and 600 seconds. We

recommend to set the value as estimated in the time line (Figure 19 on

page 28).

– UPS Wakeup Delay (Time): This is the time that the UPS must be

connected to a functioning power line before the attached systems can be

powered up. Possible delay values are 0, 60, 180, and 300 seconds.

Again, we recommend the maximum value of 300 seconds (to avoid

system boot in situations with short-time power return only). Additionally, a

percentage of full capacity for recharge may be specified as UPS Wakeup

Delay (Capacity).

Once you have set the parameters, click the OK button.

5. In the PowerChute PLUS main window (Figure 64 on page 62), select

Configuration > Application Shutdown Parameters. Figure 66 will be

displayed.
