Power, electrical, and controls

Site electrical system

To be sure that the POD solution is completely and safely integrated 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 that are 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 240e NA that are marked as hazardous voltage, per NFPA 70E in accordance with NEC (NA) and IEC (EMEA and APJ).

Grounding and bonding

WARNING: To avoid the risk of personal injury or electric shock, the HP POD 240e NA must be properly earthed (grounded), and each of the individual sections must be bonded together per NFPA 70 in accordance with NEC (NA) and IEC (EMEA and APJ).

The HP POD 240e NA must be properly earthed to be sure that a common return path for electric current exists, limit the build-up of static electricity, and absorb an unlimited amount of current without changing its potential. To properly ground the HP POD 240e NA 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.

A certified electrician must test and verify the HP POD 240e NA is properly grounded.

Grounding

The HP POD 240e NA includes the following types of grounding.

Earth ground
