This section provides the following information about determining the
location of input power cables feeding the Passport 15000 or 20000:
• "Ceiling requirements" (page 54)
• "Flooring requirements" (page 54)
Other floor criteria to consider when choosing an overhead or underfloor
route for the power cables is described in "Preparing the floor for anchor
holes" (page 101).
Consider the following before installing a NEBS 2000 frame.
• The room should be clear of potential obstructions such as beams,
columns, heating and air conditioning ducts, water pipes, lights and
video monitors.
• There should be no sprinklers in the room; however, other appropriate
fire protection should be available such as a fire extinguisher.
• The minimum ceiling clearance must be 2.5 m (8.25 feet).
The flooring can be one of the following types:
• raised subflooring, ideally with a clearance of 45.5 cm (18 inches), and a
subfloor cable management system
• non-raised floor such as concrete, which typically means installing
conduit according to your local electrical codes
