Floor loads (figure 5)
◗the floor supports the weight of each cubicle via the four 60 mm diameter pads at the bottom of the feet screwed into the corners of the frame;
◗the exact locations of the footpads are indicated in the figure;
◗normally the cubicles do not have to be secured to the floor; the footpads nevertheless have holes with an average depth of 12 mm designed for the fitting of M16 anchor bolts;
◗to determine the stresses applied by the cubicle feet on the floor, divide the cubicle weight (see the first 3 tables of this manual) by the total area of the 4 footpads (110 cm2).

The connection cables may be run in three ways:

A cutout must in this case be made in the floor for cable entry (see figure 6 for dimensions),
