60 HP StorageWorks Disk Array XP1024: Site Preparation Guide
Branch circuit requirements
When the supplied line to line voltage is in the 380 to 415-volt range, the
connection must be a five-wire WYE or STAR connection.
To protect your disk array, your building must be wired correctly. Each
supply (“hot”) conductor should 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
three-phase operation:
• 30-Amp, 50 or 60 Hz, three-phase DKC (page 40)
• 60-Amp, 50 or 60 Hz, three-phase R1 DKU (page 43)
The protective device must comply with national standards of the country
where the units are to be installed. If a protective device interrupts a supply
conductor, it must also interrupt all other supply conductors.
Overcurrent protection is not required for the neutral conductor.
