Three-Phase Ac Cabling For Europe (50 Hz); Connecting The Power-Supply Cords - HP StorageWorks XP12000 Site Prep Manual

Three-phase AC cabling for Europe (50 Hz)

Each three-phase DKU has two main disconnect devices (two main breakers for dual
power lines) so that AC power to the unit can be supplied from separate power
distribution panels with two power-supply cords.
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

All 50 Hz, European XP12000 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.
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.
