Please observe the following items when preparing the foundation:
• A suitable foundation can be a false floor, a double floor or a reinforced-concrete
foundation. The reinforced-concrete floor must be equipped with foundation rails for
supporting the panels.
• As for design and construction of the foundation, the relevant standards DIN 43 661
"Fundamentschienen in Innenanlagen der Elektrotechnik" (Foundation rails in electrical
indoor installations) and DIN 18 202 "Maßtoleranzen im Hochbau" (Blatt 3) (Measuring
tolerances in structural engineering (Sheet 3)) apply.
• Dimensions of the floor opening and the fixing points of the switchgear frame (see page 49,
"Floor openings and fixing points" and see page 72, "Fastening the switchgear to the
foundation").
• Determine level differences between the installation surfaces of the panels using a
measuring sheet, and compensate them with shims (0.5 - 1.0 mm).
