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.
ProcedureProcedure
1. If installed, release the cable management arm .
2. If the server is using a single power supply only, remove all power from the server:
a. Back up all server data.
b. Power down the server.
c. Disconnect all peripheral cables from the server.
3. Release the power cord, wires, and/or cables from the strain relief strap.
4. To access the ground cable screw, slide the power supply out of the bay.
5. Detach the ground (earthed) cable from the power supply.
