Caution notices
A caution notice calls attention to a situation that is potentially hazardous to people because of some
existing condition, or to a potentially dangerous situation that might develop because of some unsafe
practice.
Uninterruptible power supply (UPS) units contain specific hazardous
materials. Observe the following precautions if your product contains a
UPS:
• The UPS 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 UPS.
• The UPS contains its own energy source (batteries). The output
receptacles might carry live voltage even when the UPS is not
connected to an AC supply.
• Do not remove or unplug the input cord when the UPS is turned on. This
removes the safety ground from the UPS and the equipment connected
to the UPS.
• The UPS is heavy because of the electronics and batteries that are
required. To avoid injury,observe the following precautions:
– Do not attempt to lift the UPS by yourself. Ask another service
representative for assistance.
– Remove the battery, electronics assembly, or both from the UPS
before removing the UPS from the shipping carton or installing or
removing the UPS in the rack.
