European branch circuit requirements

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.
on page 41 specifies the overcurrent protective devices required for single-phase operation. All
protective devices must comply with 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 code requirements for your location and be able to connect power
to the disk array accordingly.

Connecting the European power supply cables

Connect each AC power cable to a separate receptacle on a separate circuit breaker, and 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
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
neutral conductor may cause damage to the HP system. To reduce the risk of a wrong connection, use a
plug and socket that are approved for this system. Your electrician is responsible for selecting and installing
the proper plugs and receptacles.
WARNING!
High leakage current can occur between the power supply and the unit. To avoid electrical shock, be sure
to make the protective earth connection before the supply connections.
