HP Performance Optimized Datacenter (POD) 240a Site Requirements Guide

Preparing for delivery and assembly 22
Arc Flash safety
The customer must complete an Arc Flash assessment of the HP POD 240a and the associated electrical
supply system for operation, maintenance, and so on.
Temporary lighting and power
Proper temporary lighting and power must be installed and maintained in all construction work areas.
When using temporary lighting:
• Label panels and breakers that are used for temporary lighting and power.
• The location of panels must be shown on the construction site plan and posted at the entrance to work
area.
• Lamps for general illumination must be protected from breakage, and metal shell sockets must be
grounded.
• Temporary lights must not be suspended by cords, unless they are so designed.
Storage locations and requirements
When creating a Site Plan, consider a location for storage if the site is not ready for assembly and operation.
CAUTION: The HP POD 240a must maintain 20% relative humidity to minimize condensation
and oxidation within the HP POD 240a.
Changes in ambient temperatures cause condensation in a HP POD 240a that is not operating. If the HP POD
240a is placed in storage or is non-operating mode for over 72 hours, HP recommends using one of the
following methods to minimize condensation and oxidation within the HP POD 240a:
• Desiccant unit
• Desiccant material
• Heater with a fan
• Air conditioner with heater strip
Consult with HP Services to determine the most effective method.
