Approximate Battery Times
During a power failure, the UPS battery supplies power to your
equipment, providing time to complete computing activities prior to
UPS shutdown. The duration of this time period is directly related to the
UPS battery configuration. By adding battery cabinets,you can
customize the UPS to provide enough battery time for normal processing
activities.
To prepare for a power outage at your installation, ensure that you have
sufficient battery time available. To do this, take a few minutes to
determine your approximate battery time by completing the following
steps:

Prestige 6000 (9910 EP8)
Figure 3. Determining Approximate Battery Time
1. See “Load Requirements” on page 2 for assistance in
determining the total load requirements for your UPS. Round
this number up to the next Load (VA) entry in the “Prestige
6000 with PPDM” table on page 5, and enter the number in
Figure 3.
2. In Figure 3, enter the number of battery cabinets that you
have installed. Find the intersection point of the appropriate
Load (VA) and number of battery cabinets in the “Prestige 6000
with PPDM” table on page 5. Enter this number in Figure 3,
Total Battery Time Minutes.
If changes take place in yourinstallation, such as different load
parameters or changes to battery cabinet configuration,take time to
reevaluate your approximate battery time availability.
