Weld the standard design diagonally to the foundation rails at 2 points. A floor fixing profile is
not necessary.
The welded seams must conform to the strength of an equivalent bolted joint with M10 bolts.

Fixing points (26x45 mm)
Weld the aseismic design to the foundation rails at all 4 points. A floor fixing profile is not
necessary.
The welded seams must conform to the strength of an equivalent bolted joint with M10 bolts.

① Fixing points (26x45 mm)
Observe the following items when preparing the foundation:
• Dimensions of the floor opening and fixing points of the switchgear frame
(see page 43, "Constructional data of the foundation").
• Align the base frame of the switchgear starting from a fixed point.
• Determine level differences between the installation surfaces of the panels using
a measuring sheet, and compensate with shims (0.5 - 1.0 mm).
Evenness/straightness tolerance according to DIN 43661: 1 mm for 1 m length, 2 mm over
the width of the complete switchgear.
