9. Additional functions and function setting changes for the UPS
9-2 Estimated backup time and backup time test in
Battery mode
1. Estimated backup time
The estimated time of backup in the current operating conditions is displayed on the UPS monitoring
software monitor screen.
•
In Line mode: Estimated backup time under the current charge status and load conditions is displayed.
•
In Battery mode: Estimated backup time is displayed. An accurate estimate of backup time cannot be
performed. Use this as a rough estimate.
2. Backup time adjustment
As the battery deteriorates, backup time becomes shorter. To estimate backup time, the decrease of battery
capacity needs to be measured.
•
Periodically and voluntarily perform backup operation, and measure and adjust for the battery capacity.
•
During backup time adjustment, the battery indicator blinks once per second. There is no beeping sound.
•
Scheduled backup time adjustment can be performed by setting the schedule in the UPS monitoring
software.
For example, set the schedule for once every six months as a guide.
•
Voluntary backup time adjustment can also be performed by using the UPS monitoring software.
