Connecting The Power Supply Cords (Europe); Three-Phase Ac European Branch Circuit Requirements; Wiring European Three-Phase Power Cables - HP XP20000/XP24000 Manual

CAUTION:
An HP representative should be present whenever the disk array is being connected to a new power
source for the first time.

Connecting the power supply cords (Europe)

All 50-Hz, European HP XP24000 disk array racks 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. Your electrician is responsible
for selecting and installing the proper plug.

.
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.
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.
