HP StorageWorks XP24000 Disk Array Site Preparation Guide, v01 (AE131-96002, June 2007)

Connecting the power-supply cords (Europe)
All 50 Hz, European HP XP24000 disk array cabinets are shipped with unterminated power cords.
Your electrician must select and install the correct power plug. Be sure to prepare the socket receptacles
and power cords between the power distribution board of the building and the attachment plugs for
the unit. 30-amp power cords of type H07RN-F or equivalent, with five 6 square mm conductors per
cord, are provided with the unit.
CAUTION:
Be sure to connect the power cords to the distribution panel as shown in the following figure. Improper
wiring of the neutral conductor may cause damage to the disk array. To reduce the risk of a wrong
connection, use a plug and socket that are approved for this disk array. It is your electrician's responsibility
to select and install the proper plug.
Figure 12 European power cable wiring
When connecting to 380 to 415 volt service, use a WYE configuration with neutral and ground
conductors, in addition to the three-phase wires, for a total of five wires.
WARNING!
High leakage current can occur between the power supply and the unit. To avoid electrical shock, make
the protective earth connection before the supply connections.
Three-phase AC European branch circuit requirements
When the supplied line-to-line voltage is in the 380 to 415 volt range, the connection must be a
five-wire WYE or STAR connection.
To protect the disk array, your building must be wired correctly. Each supply (“hot”) conductor must
be protected by a short-circuit protective device and by an overcurrent protective device. The tables
listed under “AC line voltage requirements” on page 47 provide specifications for the overcurrent
protective devices required for three-phase operation.
All protective devices must comply with the standards of the country where the units are to be installed.
If a protective device interrupts a supply conductor, it must also interrupt all other supply conductors.
WARNING!
Overcurrent protection is also required for the neutral conductor.
