HP Performance Optimized Datacenter (POD) 20c Site Preparation and Requirements Guide - China

Site requirements 15
• PVC
IMPORTANT: Even though some PVC grade piping materials are designed to handle the
expected water pressure, the use of PVC materials should be reviewed and approved by the
customer site engineers.
Power infrastructure installation
When determining the final location of the power connections, consider the following:
• Distance between the facility utilities and the location of the HP POD 20c
• Distance between possible UPS or generator locations and the HP POD 20c
• Requirements for routing electrical feeders (underground or overhead)
The facility power connection must be installed in compliance with local electrical codes and regulations. 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 20c.
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.
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.
A 1N electrical configuration can be achieved by providing all required electrical feeders from a common
power source and from common switchboards, and transformers.
A 2N electrical configuration can be achieved by feeding parallel power paths from independent power
sources, switchboards, and transformers.
IMPORTANT: The required neutral must be provided as part of the 380-415VAC Y direct
connection to the HP POD 20c.
