HP StorageWorks XP12000 Disk Array Site Preparation Guide
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. Table 23
(page 70)
,
Table 24
(page 70)
, Table 26
(page 71)
, and Table 27
(page 72)
provide
specifications for 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.
Note
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 the 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.
