Site requirements 15
• 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 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: The required neutral must be provided as part of the 380-415VAC Y direct
connection to the HP POD 20c.
IMPORTANT: All 3-Phase Wye feeders for the HP POD 20c require that the neutrals and the
equipment grounding conductors remain isolated. Bonding of the two conductors is allowed at
the power source only.
