WARNING:
To reduce the risk of electric shock, fire, and damage to the equipment, you must
install this product in accordance with the following guidelines:
• This power supply is intended only for installation in Hewlett Packard Enterprise servers
located in a restricted access location.
•
This power supply is not intended for direct connection to the DC supply branch circuit. Only
connect this power supply to a power distribution unit (PDU) that provides an independent
overcurrent-protected output for each DC power supply. Each output overcurrent-
device in the PDU must be suitable for interrupting fault current available from the DC
power source and must be rated no more than 60A.
• The PDU output must have a shut-off switch or a circuit breaker to disconnect power for
each power supply. To completely remove power from the power supply, disconnect power
at the PDU. The end product may have multiple power supplies. To remove all power from
the product, disconnect the power for each power supply.
•
In accordance with applicable national requirements for Information Technology Equipment
and Telecommunications Equipment, this power supply only connects to DC power sources
that are classified as SELV or TNV. Generally, these requirements are based on the
International Standard for Information Technology Equipment, IEC 60950-1. In accordance
with local and regional electric codes and regulations, the DC source must have one pole
(Neutral/Return) reliably connected to earth ground.
• You must connec
t the power supply ground screw located on the front of the power supply
to a suitable ground (earth) terminal. In accordance with local and regional electric codes
and regulations, this terminal must be connected to a suitable building ground (earth)
terminal. Do not rely on the rack or cabinet chassis to provide adequate ground (earth)
continuity.
WARNING: To reduce the risk of personal injury from hot surfaces, observe the thermal
labels on each power supply or module.
WARNING: To reduce the risk of injury from electric shock hazards, do not open power
supplies. Refer all maintenance, upgrades, and servicing to qualified personnel.
WARNING:
Remove power from the power supply before performing any installation steps or
maintenance on the power supply.
CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be sure that
you are properly grounded (earthed) before beginning any installation procedure.
