5.4 Periodic Battery Check
After the first 3 years, perform a load test every 6 months to confirm the capacity
of the battery system.
To perform a load test follow these steps:
1. Turn OFF the ac input power to the UPS so that the UPS draws power from
the batteries.
2. With a full-load on the UPS, battery capacity may be considered adequate if
the batteries discharge for at least 7 minutes before the red "Low Battery"
status light illuminates.
3. As soon as the red "Low Battery" status light illuminates, turn ON the ac
input power for the UPS to avoid interrupting power to the load.
If a full-load is not used to test the battery capacity, determine the back-up time
achieved during the first year of operation (assuming the load remains the same).
Compare these results with future tests.
5.5 Storage Procedures
If the 2T-HA10F-CD UPS is going to be stored, the following guidelines
must
be
followed to protect the batteries:
1. Charge the batteries fully before the UPS is stored by connecting the UPS to
an ac source and operating it for 12 hours with all three circuit breakers in
the ON position.
2. Turn the UPS OFF. Ensure that the ac input circuit breaker and the battery
circuit breaker on the front panel, and the battery unit circuit breaker on the
rear panel of the battery unit are OFF (not tripped or ON).
3. Avoid storage temperatures above 27°C (80°F). The preferred storage
temperature is 21°C (70°F).
4. Every 90 days, connect the UPS to an ac source and operate it for 12 hours
to recharge the batteries. The batteries may suffer damage if they are not
recharged every 90 days during storage. Be sure that the ac input circuit
breaker and the battery circuit breaker on the front panel, and the battery
unit circuit breaker on the rear panel of the battery unit are OFF, not tripped
or ON, when the UPS is returned to storage.
5. When moving, storing, or operating the UPS it must be kept in an upright
position.
