Important Safety Information For the Power 
Distribution Unit (PDU)
Retain and follow all product safety and operating instructions. Observe all warnings on 
the product and in the operating instructions. To reduce the risk of bodily injury, electric 
shock, fire, and damage to the equipment, observe all precautions included in this 
guide.
To reduce the risk of electric shock and/or equipment damage when servicing PDU: 
The routine maintenance and service of PDU must be performed by individuals who 
are knowledgeable about the procedures, precautions, and hazards associated with 
AC power products. It should only be performed by a licensed electrician in 
accordance with National Electrical Code (NFPA70 Article 310) in North America 
and national wiring regulations. 
Do not attempt to make any modifications to PDU assembly. Improper repairs or 
modifications can create a safety hazard. 
Verify that the AC power supply branch circuit that provides power to the rack is 
not overloaded. This will reduce the risk of personal injury, fire, or damage to the 
equipment. The total rack load should not exceed 80 percent of the branch circuit 
rating. Consult the electrical authority having jurisdiction over your facility for 
installation requirements.
If the product sustains damage requiring service, disconnect the product from 
the AC electrical outlet and refer servicing to a HP authorized service provider. 
Examples of damage requiring service include:
•
The power cord, extension cord or plug has been damaged.
•
Liquid has been spilled on the product.
•
The product has been exposed to rain or water.
To reduce the risk of electric shock or damage to the equipment when maintaining or 
servicing PDU, observe the following precautions:
•
Disconnect all power supply cords from the source. Remove all watches, rings, or 
loose jewelry when working in hot-plug areas of an energized system.
•
Never use the product in a wet location. Avoid inserting foreign objects through 
openings in the product.
