14 HP BladeSystem p-Class Enclosure Installation Guide
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 this equipment, HP
recommends the use of a 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 to supply
power to this equipment is not recommended.
