Removing the 2145 UPS-1U

DANGER

Uninterruptible power supply units contain specific hazardous materials. Observe the following

precautions if your product contains an uninterruptible power supply:

v 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.

v 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.

v 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.

v 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.
