Connecting the power supply cords (Europe)

50-amp single phase power cords for Europe
Each 50-amp HP XP24000 disk array rack has two power supply cords. The power cords included
with the unit are type H07RN-F or equivalent with three 10 square mm conductors.
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.

30-amp single-phase power cords for Europe
Each 30-amp HP XP24000 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 previous 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.
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.

European single-phase AC 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. 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.
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
