REPLACING THE BATTERY
Servicing of batteries should be performed or supervised by personnel knowledgeable about batteries and required precautions.
When replacing batteries, replace with the same type and size battery.
To replace the battery:
1. Turn off all connected loads, then turn off the UPS and unplug the input
power cord. (Batteries are NOT hot-swappable.)
2. Carefully lay the UPS on its left side, as shown in the diagram.
3. Use a #1 Phillips head screwdriver to remove the four screws from the
right-side cover, then pull up the right-side cover and remove it.
4. Remove the black wire from the negative (-) terminal and the red wire from
the positive (+) terminal.
5. Gently remove the battery from the UPS.
Attention: Risk of Electric Shock.
6. Verify that the replacement battery matches the dimensions and battery
specification.
7. Connect the battery leads to the new battery. 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. Take care not to short-circuit the positive and negative
battery terminals while replacing the battery.
8. Place the battery in the UPS.
9. Ensure correct alignment of front panel, then reattach the right-side cover.
Evenly tighten the four screws from Step 3. (Do NOT over tighten screws)
Dispose of the old battery properly at an appropriate recycling facility.
