30-amp single phase power cords for Europe

Each 30-amp HP XP12000 disk array rack has four power supply cords. The power cords included
with the unit are type H07RN-F or equivalent with three 6 square mm conductors.
CAUTION:
Be sure to connect the power cords to the distribution panel as shown in
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.
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.

Single-phase AC 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. The tables
listed in "AC line voltage
for single-phase operation. All protective devices must comply with national standards of the country
where the units are 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.
In many cases, local codes do not allow a branch circuit fitted with a 50-amp receptacle or connector
to be protected by an overcurrent-protection device with a rating lower than 50 amps. You can order
an HP XP12000 disk array with the 30-amp power option to comply with these local codes. Your
electrician knows the appropriate code requirements for your location/site.
