Charging The Battery - Delta 3KVA User Manual

3. Charging the battery

The battery charger of the UPS automatically charges the battery whenever the power
cord of UPS is connected to a acceptable utility power.
When UPS is running for the first time, charge the UPS for at least 6 hours to ensure
batteries inside are fully charged before operation.
You may immediately use the UPS without having to wait for the batteries to be fully
charged. However, it is advisable not to do this as UPS will have a shorter back-up time
than expected if such action is taken.
Connecting the battery bank
1. Utilize the battery connection cable packed with the battery bank.
2. Connect on one end of the cable to the external battery connector of UPS, and the
other end to that of the battery bank.
3. Warning: For safety reason, the manufacturer suggests that ONE UPS
CONNECTS AS MANY AS FIFTEEN EXTERNAL BATTERY BANKS.
