Battery

The POWER + battery bank is used as a backup in the event that the utility ac input fails.
Batteries are charged by the rectifier which supplies both the inverter and the battery charger.
For systems from 10kVA through 40kVA, the batteries may be housed internally; however for systems
from 50kVA through 100kVA, or for sites where a long backup duration is required, the batteries are
housed in an external cabinet. The battery cabinet should be installed as close to the UPS as is practically
possible.
Protect the batteries from moisture, dampness, and foreign substances. The temperature of the battery's
environment influences the batteries' useful lifetime.
