HP Performance Optimized Data Center (POD) 240a manual Site electrical system

Page 14

IMPORTANT: To provide power to the HP POD 240e NA, external transformers and switchboards might be required. This equipment must be designed and installed to adhere with local, state, and national codes, and installed by contractors with licensing required by the local jurisdiction; city, township, and state.

For all site preparation drawings, see the HP Site Preparation Drawing Package (on page 22).

Site electrical system

To be sure that there is a complete and safe integration of the HP POD solution within your facility, HP requires that you complete the following actions for the installed electrical system before 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.

Electrical power system configuration

A preliminary meeting with the HP POD Electrical Engineering team is necessary to discuss your decision concerning capacity limitations and the impacts of this decision on the electrical design.

When determining the final location of the power connections, consider the following:

Distance between the facility utilities and the location of the HP POD 240e NA

Distance between possible UPS or generator locations and the HP POD 240e NA

Requirements for routing electrical feeders (underground or overhead)

The facility power connection must be installed in compliance with local electrical codes and regulations. The HP reference electrical installation design is based on a maximum distance of 15.2 m (50 ft) or a line of sight between the disconnect and the HP POD 240e NA. You are required to discuss your decision concerning capacity limitations, and the impacts of this decision, on the electrical design with the POD Electrical Engineering Team.

A 1N electrical configuration can be achieved by providing all of the required electrical feeders from a common power source, common switchboards, and transformers.

A 2N electrical configuration can be achieved by feeding parallel power paths from independent power sources, switchboards, and transformers.

IMPORTANT: All 3-phase wye feeders for the HP POD 240e NA require that the neutrals and the equipment grounding conductors remain isolated. Bonding of the two conductors is allowed at the power source only.
