Retaining Screws

6.Disconnect the battery positive (red) wire from the battery positive (+) terminal.

7.Turn the power switch on, to discharge the UPS.

8.Disconnect the battery negative (black) wire from the battery negative (-) terminal.

9.Remove the defective battery from the battery compartment.

10.Install the new battery into the battery compartment.

11.Reconnect the battery negative (black) wire to the battery negative (-) terminal.

12.Reconnect the battery positive (red) wire to the battery positive (+) terminal. Note: Some spark- ing may occur, this is normal.

13.Reinstall the battery compartment door and the retaining screws.

14.Charge the UPS for 4 to 8 hours to ensure the UPS performs expected runtime.

Note: Batteries are consider HAZARDOUS WASTE and must be disposed of properly at an ap- propriate recycling facility or return them to the supplier in the packing material for the new bat- tery. Contact your local government for more information about proper disposal and recycling of batteries.

Note: Replace the batteries with the same number and type as originally installed in the UPS. These batteries have pressure-operated vents. These UPS contain sealed non-spillable lead-acid batteries.
