temperature exceeds this limit for greater than 3 minutes. To recover the system, AC power cycle
the D6020.
CAUTION:
Do not permit optional equipment to impede airflow around the chassis or to increase the
internal rack temperature beyond the maximum allowable limits.
Do not exceed the manufacturer's TMRA.

Power requirements

Installation of this equipment must comply with local and regional electrical regulations governing
the installation of IT equipment by licensed electricians. This equipment is designed to operate
in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA 75, 1992
(code for Protection of Electronic Computer/Data Processing Equipment). For electrical power
ratings on options, refer to the product rating label or the user documentation supplied with that
option.
WARNING!
overload the AC supply branch circuit that provides power to the rack. Consult the electrical
authority having jurisdiction over wiring and installation requirements of your facility.
CAUTION:
regulating UPS. This device protects the hardware from damage caused by power surges and
voltage spikes and keeps the D6020 in operation during a power failure.
While installing more than one D6020, you may need to use additional power distribution devices
to safely provide power to all devices. Observe the following guidelines:
Balance the D6020 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 each power supply in the D6020.

Grounding requirements

This equipment 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 this equipment, HPE 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.
To reduce the risk of damage to the equipment when installing third-party options:
To reduce the risk of personal injury, fire, or damage to the equipment, do not
