DANGER
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 representa-
tive. 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. (D007)

Energy hazard present. Shorting might result in system outage and possible physical injury.

CAUTION
Lead-acid batteries can present a risk of electrical burn from high, short-circuit current. Avoid battery contact with metal materials;
remove watches, rings, or other metal objects, and use tools with insulated handles. To avoid possible explosion, do not burn.
