Removing the 2145 UPS battery

Follow all safety notices when you are removing the 2145 UPS battery.

DANGER

Uninterruptible power supply units contain specific hazardous materials. Observe the following precautions if your product contains an uninterruptible power supply:

• The uninterruptible power supply contains lethal voltages. All repairs and service must be performed only by an authorized service support representative. There are no user serviceable parts inside the uninterruptible power supply.
• The uninterruptible power supply contains its own energy source (batteries). The output receptacles might carry live voltage even when the uninterruptible power supply is not connected to an ac supply.
• Do not remove or unplug the input cord when the uninterruptible power supply is turned on. This removes the safety ground from the uninterruptible power supply and the equipment connected to the uninterruptible power supply.
• The uninterruptible power supply is heavy because of the electronics and batteries that are required. To avoid injury, observe the following precautions:
  • Do not attempt to lift the uninterruptible power supply by yourself. Ask another service representative for assistance.
  • Remove the battery, electronics assembly, or both from the uninterruptible power supply before removing the uninterruptible power supply from the shipping carton or installing or removing the uninterruptible power supply in the rack.
