• Provide a separate electrical circuit for the storage system.
Electrical grounding requirements
The storage system must be grounded properly for proper operation and safety.
In the United States, you must install the equipment in accordance with
NFPA 70, 1999 Edition (National Electric Code), Article 250, as well as any
local and regional building codes. In Canada, you must install the equipment in
accordance with Canadian Standards Association, CSA C22.1, Canadian
Electrical Code. In all other countries, you must install the equipment in
accordance with any regional or national electrical wiring codes, such as the
International Electrotechnical Commission (IEC) Code 364, parts 1 through 7.
Furthermore, you must be sure that all power distribution devices used in the
installation, such as branch wiring and receptacles, are listed or certified
grounding-type devices.
Because of the high ground-leakage currents associated with multiple storage
system connected to the same power source, HP recommends the use of a power
distribution unit (PDU) that is either permanently wired to the building’s branch
circuit or includes a nondetachable cord that is wired to an industrial-style plug.
NEMA locking-style plugs or those complying with IEC 60309 are considered
suitable for this purpose. Using common power outlet strips for the storage
system is not recommended.
