The switchgear must be firmly bolted or welded together with the foundation of the switchgear
room. The fastening and the foundation must absorb the stress arising from vibrations and faults
such as a short circuit in the grid or internal arcing. The switchgear must not detach from the
foundation as a result of such stress.
Depending on the type of fastening, the following work operations are required:
1. Bring the panel into position.
2. Remove the cable compartment cover [▶ Page 125, "Removing and mounting the cable
compartment cover"].
3. If required, remove the cross member [▶ Page 126, "Removing and mounting the cross
member"].
4. The panel must rest flush on the foundation; if necessary, lay shims underneath.
5. Prepare the foundation for fastening; e.g. mark holes and drill.
6. Remove pollution such as drilling dust or drilling chips.
7. Bolt or weld the panel to the foundation.
8. Protect welded seams against corrosion.
Fixing points
The panel frames have cutouts for fastening the panels [▶ Page 69, "Floor openings and fixing
points"].
1. Fasten the panels at the following fixing points using bolts M8 (see example):
▪ Fasten end panels at least at 4 fixing points; 1 x at the front, 1 x at the rear, and 2 x laterally.
▪ Fasten intermediate panels at least at 2 fixing points; 1 x at the front and 1 x at the rear.
▪ Fasten air-insulated metering panels at all available fixing points.
▪ Fasten panels with floor covers at all available fixing points.
