Pre-Installation
Room preparation
During the design of the data center, consider ease of entry for the equipment, floor loading factors, and
accessibility to piping and wiring. In addition, the room temperature and humidity combination should
conform to the environmental operating envelope as defined in the following graphics.
Seal the room with a vapor barrier to minimize moisture infiltration. Polyethylene film is recommended
for ceiling and wall applications. Apply rubber- or plastic-based paints to concrete walls and floors.
Insulate the room to minimize the influence of exterior heat loads. Reduce fresh air to the minimum
required by local and national codes and regulations. Fresh air imposes extreme load variation on the
cooling equipment from summer to winter and causes increased system operating costs.
Air distribution
The equipment distributes air in a back-to-front discharge pattern, removing hot air from a hot aisle and
discharging cooled air into a cold aisle.
Note: The equipment is designed for free air discharge or for use with the Rack Air
Containment System or Hot Aisle Containment System. The equipment is not intended to be
connected to a duct system.
Incoming power supply requirements
Automatic Transfer Switch (ATS). The function of the ATS is to
transfer the load from feed A to feed B if the power is lost on feed A.
• Feed A (Primary Power Feed) supplies power to all functions in the
equipment.
• Feed B (Redundant Power Feed) supplies power to all functions in
the equipment.
CAUTION
ELECTRICAL HAZARD
The equipment requires three-phase electrical service. Electrical service must conform to
local and national electrical codes and regulations. The equipment must be grounded.
Failure to follow these instructions can result in equipment damage.
