Manual
voltage and current rating for the cord should be greater than the voltage and current rating marked
on the product. In addition, the diameter of the wire must be a minimum of 1.00 mm

or 18 AWG,
your maximum length may be up to 3.66 m (12 ft).
WARNING!
To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding plug. The grounding plug is an important safety feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.
• Unplug the power cord from the power supply to disconnect power to the equipment.
• Do not route the power cord where it can be walked on or pinched by items placed against it.
Pay particular attention to the plug, electrical outlet, and the point where the cord extends from
the storage system.
To connect AC power cords:
1. Connect the power cords to the power supplies.
2. Connect the power cords to the AC power source.
Electrical grounding requirements
The enclosure 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 enclosures 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 enclosure is not recommended.
