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:
Load Load
Requirements
UPS Model
(VA)
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
Product Models" table on page 5, and enter the number in
Figure 3.
2. If you have installed battery cabinets, skip to Step 3.
If you do not have any battery cabinets, enter your UPS Model
number in Figure 3 (for example, 650, 650 EXT, 1250 EXT,
1500 EXT). Find the appropriate Load (VA) and UPS Model in
the "Prestige Product Models" table on page 5. The
intersection of these two parameters shows the approximate
number of minutes of battery time your UPS Model will have at
full load (enter this number in Figure 3, Total Battery Time
Minutes).
3. 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 with
Additional Battery Cabinets" table on page 6. Enter this
number in Figure 3, Total Battery Time Minutes.
If changes take place in your installation, such as different load
parameters or changes to battery cabinet configuration, take time to
reevaluate your approximate battery time availability.
NOTE For detailed information regarding calculation of 9910 UPS battery capacity and
run time for your load, reference: "AS/400 Physical Planning," SA41-5109, "AS/400
Advanced Series Backup and Recovery - Advanced," SC41-4305 (see Chapter 10), or
AS/400e series Backup and Recovery," SC41-5304 (see Chapter 37).
