Battery Times for the UPS and BIM
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 modules, you can customize the UPS to provide enough battery time
for normal processing activities.
