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
HPE 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 80A.
• The HPE Synergy 12000 Frame 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.
