Power Requirements
WARNING: To reduce the risk of personal injury, fire, or damage to the
equipment, do not overload the AC supply branch circuit that provides power to
the rack. Consult the electrical authority having jurisdiction over your facility
wiring and installation requirements.
IMPORTANT: At low line input voltage (typically 100-130 VAC), the combined input
current of multiple power supplies may exceed the rating of the building supply circuit.
Therefore, some local electrical authorities may require either one 15-Ampere circuit for
each power supply or one 20-Ampere circuit for a pair of power supplies. If a third power
supply is used, a separate branch circuit will be necessary.
■ The power load needs to be balanced between available AC supply
branch circuits.
■ The overall system AC current load must not exceed 80 percent of the
branch circuit AC current rating.
■ If power strips are used, the load should not exceed 80 percent of the
power strip’s marked electrical current rating.
The installation of this equipment shall be in accordance with local/regional
electrical regulations governing the installation of information technology
equipment by licensed electricians. This equipment is designed to operate in
installations covered by the National Electric Code (ANSI/NFPA 70, 1993)
and the code for Protection of Electronic Computer/Data Processing
Equipment (NFPA-75, 1992).
For electrical power ratings on options, refer to the product’s rating label or
user documentation supplied with that option.
Grounding
For proper operation and safety, this equipment must be properly grounded in
accordance with NFPA 70-1993, Article 250. All power distribution devices,
branch wiring, and receptacles must be “Listed” grounding-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.
