European Ac Power Cabling; European Single-Phase Power Connection - HP XP20000/XP24000 Manual

European AC power cabling

Each XP20000 rack requires 20-amp, single-phase 200 VAC power supplied by four power cords
with plugs, four receptacles, and four main disconnect devices (circuit breakers). If the second rack
contains only one disk chassis, only two power cords and breakers are required, but four are
recommended if you plan to add another disk chassis later.
The XP20000 disk array comes from the factory with the AC power cables and plugs or stripped
ends based on the power option ordered. The opposite end of the power cord connects to the XP20000
power distribution unit (PDU) input, which is a type IEC 320-C20 connector.
European branch circuit requirements
To protect the disk array, the building must be wired correctly. Each supply ("hot") conductor must
be protected by a short-circuit protective device and by an overcurrent protective device.
on page 55 specifies the overcurrent protective devices for single-phase operation. All protective
devices must comply with the national standards of the country where the units are to be installed. If
a protective device interrupts any supply conductor, it must also interrupt all other supply conductors.
Overcurrent protection is also required for the neutral conductor.
Your electrician should know the appropriate code requirements for your location/site and should be
able to wire power distribution to the XP20000 disk array accordingly.
Connecting the European power supply cables
Connect each AC power cable to a separate receptacle on a separate circuit breaker. Connect each
pair of power cords (the left pair and the right pair) to separate distribution panels to ensure power
fault tolerance. Single-phase power cable wiring is shown in the figure below.
CAUTION:
Do not apply power until instructed to do so by HP. An HP representative should be present whenever
the disk array is being connected to a new power source.

.
CAUTION:
Be sure to connect the power cords to the distribution panel as shown in
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 plugs and receptacles.
