WARNING: To reduce the risk of electric shock, fire, and damage to the equipment, this
product must be installed in accordance with the following guidelines:
This power supply is intended only for installation in HP servers located in a restricted
•
access location.
This power supply is not intended for direct connection to the DC supply branch circuit. It
•
should only be connected to a power distribution unit (PDU) that provides an independent
overcurrent-protected output for each DC power supply. Each output overcurrent-protected
device in the PDU must be suitable for interrupting fault current available from the DC
power source and must be rated no more than 50A.
This power supply is designed to be connected only to a DC power source that can be
•
classified as SELV or TNV, in accordance with applicable national requirements for
Information Technology Equipment and Telecommunications Equipment. Generally, these
requirements are based on the International Standard for Information Technology
Equipment, IEC 60950, and/or the European Telecommunication Standard ETS 300 132-
2. The DC source is to have one pole (Neutral/Return) reliably connected to earth ground
in accordance with local/regional electric codes and/or regulations.
The green/yellow lead of the power cable assembly must be connected to a suitable
•
ground/earth terminal. This terminal must be connected to a suitable building
ground/earth terminal in accordance with local/regional electric codes/regulations. Do
not rely on the rack or cabinet chassis to provide adequate ground/earth continuity.
WARNING: To reduce the risk of personal injury or damage to the equipment, the installation
of power supplies should be performed only by individuals who are qualified in servicing
server equipment and trained to deal with products capable of producing hazardous energy
levels.
WARNING: To reduce the risk of personal injury from hot surfaces, observe the thermal labels
