Electrical Grounding Requirements - Inspur SA5112M4 User Manual

When installing more than one server, you may need to use additional power distribution
devices to safely provide power to all devices. Observe the following guidelines:
● Balance the server power load between available AC supply branch circuits.
● Do not allow the overall system AC current load to exceed 80 percent of the branch circuit
AC current rating.
● Do not use common power outlet strips for this equipment.
● Provide a separate electrical circuit for the server.

5.1.4 Electrical Grounding Requirements

The server must be grounded properly for optimal 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, and 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 servers connected to
the same power source, Inspur 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 for the server is not
recommended.
