.
The primary floor and wall risers located at raised floor level must be coated with dustproof
paint or varnish. The floor must be sloped and equipped with a drain.
1.9.2.
Raised Floor
CAUTION
A raised floor compliant with the Standards NF P67 103-1 and 103-2 in force is mandatory,
in particular for the installation of a Cooling Unit.
CAUTION
If the air-conditioning unit(s) is (are) placed on brackets in the room, it is mandatory to
electrically isolate these brackets from the raised floor slabs, crossbeams, and actuators.
A raised floor allows even distribution of the overall system load and provides a plenum
space for cabling and air-conditioning.
The raised floor must be made of 60 cm x 60 cm, removable, interchangeable, square slabs
supported by adjustable flat-head actuators (18 per silo), fitted with electrically conductive
rubber pads.
The structure must be reinforced by intermediate crossbeams or T-beam section spars,
according to slab cut-outs and the hardware load.
At the actuator base, the structure must be meshed with > 10mm

section, flat, tin-plated
copper braiding compliant with the Standard NF EN 50.147-2 in force.
