D2 for front (F) or rear (R) input.
D4 for side input.
* Each cable should be checked against the manufacturer's data.
Dimensions in mm.
For anti-vermin cubicles, the minimum value
of D2 will be the cable's curvature radius.
4.5 Fastening to the floor
Before assembling the cubicles, the floor must be carefully
levelled to prevent any deformation which may make
it difficult to connect it to the rest of the cubicles in the
assembly.
The cubicles can be fastened to the floor in two ways:
