Power
IMPORTANT: To provide power to the HP POD 240a, external transformers and switchboards may 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 6) included on the documentation CD.
Power requirements
The HP POD 240a can be installed as a single source 1N load by providing all required feeders from one common power sources and from common switchboards and transformers, if required. A fully redundant 2N installation can be achieved by feeding the parallel power paths from independent power sources, switchboards and transformers if required.

External power source
When determining the final location of the power connections, consider the following:
Distance between the facility utilities and the location of the transformer and switchboard
Distance between the transformer and switchboard and the HP POD 240a
Distance between the UPS/Generator locations and the HP POD 240a switchboard
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 line of sight between the switchboard and the HP POD 240a.
