WARNING: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:
The HPE 800 W Flex Slot -48 VDC hot-plug power supply is intended only for installation in
Hewlett Packard Enterprise servers located in a restricted access location.
The HPE 800 W Flex Slot -48 VDC hot-plug 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-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 30 A.
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. Disconnect the power for each power supply, if there are multiple power supplies.
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/IEC 62368-1. 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 connect 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.
PrerequisitesPrerequisites
Before you perform this procedure, make sure that you have the following items:
No. 1 Phillips screwdriver
If you are replacing the factory installed ground lug, use the KST RNB5-5 crimp terminal ring or equivalent. Use an M5-0.80 x 8
screw to attach the ground lug to the power supply.
