Installing The Support Rails For A 2145 Ups-1U - IBM SAN Volume Controller Hardware Maintenance Manual

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.
