For binding switchgear dimensions, please refer to the order documentation
(dimension drawing, front view).
For data, see Page 48, "Switchgear versions - Dimensions and weights".
The switchgear must be fixed to the foundation so as to guarantee sufficient
pressure resistance. The panels can be fastened to the foundation in
the following ways:
• Bolted to foundation rails.
• Welded to foundation rails.
• Screwed into the concrete using size 10 dowels if there are no foundation rails
available.
We recommend to fasten the switchgear with at least 4 bolts size M8 in each panel.
The base pieces of the panel frames contain cutouts for fastening the switchgear
(see dimension drawing).
Fig. 44: Switchgear fastening to the foundation
Fasten each panel to the foundation as follows:
For direct fastening to the concrete, drill holes in the foundation and insert
size 10 dowels.
Place shims in the spaces between the panel frame and the foundation in the area of
the fastening cutouts, so that the switchgear is not distorted when it is bolted on,
and the seam does not cover any air-filled gaps when the switchgear is welded on.
Bolt or weld the switchgear to the foundation.
Remove any dirt, as extreme cleanliness is required during installation.
Paint welding seams to protect them against corrosion.
Mount the lower partition after having fixed the panels on the floor. The partitions for
the individual panels are supplied separately, see supplementary equipment.
The partition is mounted on site.
Remove the cable compartment covers.
Fasten the lower partition. To do this, use M6 Torx bolts.
Tightening torque: Maximum 12 Nm.
