HP ProLiant DL740 Server - Manual (Page 50)

Installing the Server in a Rack
Grounding Requirements
WARNING: To reduce the risk of electrical shock from high leakage currents, a
reliable, grounded (earthed) connection is essential before connecting the unit
to an AC supply.
For proper operation and safety, this equipment is required to be correctly grounded.
In the United States, install the equipment in accordance with ANSI/NFPA 70, 1999,
Article 250, and with any local and regional building codes. In Canada, the
equipment should be installed in accordance with Canadian Standards Association,
CSA C22.1, Canadian Electrical Code. In all other countries, the installation should
follow any regional or national electrical wiring codes, such as the International
Electrotechnical Commission (IEC) 364, parts one through seven. All power
distribution devices used in the installation, including branch wiring, receptacles, and
so on, should be Listed or Certified ground-type devices.
Due to the higher ground leakage currents associated with the equipment, HP
recommends the use of a Power Distribution Unit (PDU) that provides a
supplementary ground conductor. This supplementary ground conductor should be
permanently connected to a suitable building ground terminal. The use of common
power outlet strips for this equipment is not recommended.
