Grounding Requirements

WARNING: To reduce the risk of electrical shock due to high leakage currents,
a reliable grounded connection (earthed) is essential before connecting the unit
to an AC supply.
For proper operation and safety, this equipment is required to be properly
grounded. In the United States, install the equipment in accordance with
ANSI/NFPA 70, 1999, Article 250, as well as 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,
Compaq 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.
NOTE: For further information on grounding methods in the workplace, see Appendix B,
"Electrostatic Discharge."
