30-amp power cords
Each 30-amp HP Disk Array XP1024 cabinet has four power-supply cords.
The power cords included with the unit are type H07RN-F or equivalent
2
with three 6 mm conductors.
High leakage current may occur between the power supply and the unit. To
avoid an electrical shock, be sure the protective earth connection is made
before the supply connections.
To protect your 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 following tables list
the current specifications for the overcurrent protective devices required for
single-phase operation:
• 40-Amp, 50 or 60 Hz, single-phase DKC
• 30-Amp, 50 or 60 Hz, single-phase DKC
• 50-Amp, 50 or 60 Hz, single-phase DKU
• 30-Amp, 50 or 60 Hz, single-phase DKU
The protective device must comply with national standards of the country
where the units is to be installed. If a protective device interrupts a supply
conductor, it must also interrupt all other supply conductors.
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 your HP
Disk Array XP1024 with the 30-amp power option to comply with these
local codes. Your electrician knows the appropriate code requirements for
your location/site.
