Power, electrical, and controls

Site electrical system

To ensure a complete and safe integration of the HP POD solution with your facility, HP requires that you

complete the following actions for the installed electrical system prior to the installation of the HP POD

solution:

• Short circuit analysis

• Arc flash study

• Circuit breaker coordination study

These actions must be performed for all associated parts of the electrical power train. The majority of the

details and factors required to complete these studies are associated with the existing installed facility

infrastructure.

CAUTION: Failure to complete these studies can cause serious issues with the electrical

integration of the POD into your electrical system.

Power safety

WARNING: To avoid the risk of personal injury or loss of life, all personnel must comply with PPE

requirements when opening or working inside areas of the HP POD 20c that are marked as

hazardous voltage, in accordance with NFPA 70 (NA) and IEC (EMEA and APJ).

Grounding

WARNING: To avoid the risk of personal injury or electric shock, the HP POD 20c must be

properly earthed (grounded) in accordance with NFPA 70 (NA) and IEC (EMEA and APJ).

The HP POD 20c must be properly earthed to ensure a common return path for electric current, limit the

build-up of static electricity, and absorb an unlimited amount of current without changing its potential. To

properly ground the HP POD 20c to the earth, you must connect the POD to building steel, a ground rod, or

a properly installed ground well that is connected to a building’s grounding system. The grounding electrode

conductor connection point is located on the cold aisle side adjacent to the power cabinet.
