hot-swappable).
2. Use a Phillips head screwdriver to remove the two top cover screws from
the back of the UPS.
3. Slide the top panel backward 1/2" (13mm). Slide the front panel upward,
then pull outward to remove it.
4. Gently pull the batteries out of the UPS.
5. Remove the black wire from the negative (-) terminal and the red wire from
the positive (+) terminal.
6. Verify that the replacement battery matches the dimensions and battery
type in the Specifications section below.
7. Connect the battery leads to the new batteries. Be sure to reconnect the
red wire to the positive (+) terminal and the black wire to the negative (-)
terminal.
Note: Small sparks may occur at the battery connectors during
reconnection.
8. Slide the batteries into the UPS.
9. Reposition the front panel and slide downward until it slides into place.
Slide the top panel forward until flush with the front panel. Reinsert the two
top cover screws removed in Step 2.
Dispose of the old batteries properly at an appropriate recycling facility.
