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.	Steps 2 and 3
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)
