INSTALLATION PROCEDURE FOR EXTENDED BATTERY BANKS
1. Remove the battery fuse located on the UPS rear panel. See illustration above.
2. Locate the battery interconnect cable(s).
3. Connect one end of the battery interconnect cable to the UPS battery
connector. Connect the other end of the cable to the top battery connector on the first
battery bank. See illustration above.
4. If a second battery bank is to be connected, connect one end of the second battery
interconnect cable to the bottom battery connector on the first battery bank and
connect the other end of the cable to the top battery connector of the second battery
bank. (See illustration above)
5. Follow the instructions in the proceeding step for additional battery banks.
6. Reinstall the battery fuse. A popping sound may be heard when inserting the fuse.
This is normal as the battery banks are pre-sharing the UPS.
7. For all battery banks that have the battery charger option installed from the factory,
perform the following:
a. Verify the battery charger circuit breaker is in the off (down) position.
b. On the battery bank nameplate label located on the rear panel, verify the
battery charger input voltage matches your utility source (120Vac or
230Vac).
c. Connect the input line cord(s) to the battery bank(s) power inlet.
d. Plug the other end of the power cord into a utility receptacle.
e. Turn on the battery charger circuit breaker(s) (up).
f. The batteries in the external battery banks are now being charged.
NOTE: Internal battery bank chargers do not charge the batteries inside the UPS.
When the battery banks and UPS need to be shutdown for more than
two weeks, turn off the battery charger circuit breaker, disconnect the
interconnecting cables and remove the battery fuse from the UPS battery or
damage may occur.
