Testing New Batteries
NOTE
The batteries must be fully charged and the UPS must not be in Battery mode to
perform the battery test.
NOTE
For an accurate battery test, test the UPS with at least 10% load applied to the UPS.
To test the new batteries:
1.
Plug the UPS into a power outlet (apply utility power on hardwired
models) for 48 hours to charge the battery.
2.
Select MENU from the system status screen, then select
CONTROL, BATTERY TEST, and SCHEDULE TEST.
The UPS verifies the battery converter and schedules the battery
test to occur during the next appropriate stage in the charging cycle
(or immediately if possible).
During the battery test, the
indicator flashes rapidly.
3.
To view a report of the latest scheduled battery test, select MENU
from the system status screen, then select CONTROL,
BATTERY TEST, and TEST REPORT.
Replacing the Electronics Module
Consider all warnings and notes before replacing the electronics module.
The electronics module can be replaced easily without turning the UPS
off or disconnecting the load. The UPS automatically transfers to Bypass
mode. Battery mode is not available; however, the utility power
continues to be passively filtered by the UPS.
If you prefer to remove input power to change the electronics module,
see “UPS Shutdown from Normal or Bypass Mode” on page 71.
