If they are transported vertically

 (figure 3.16), they should be lifted by the short side 

and placed directly in their final position (figure 3.17).

3.7.1.  Assembling Bottom Plates 

After checking that the ground is correctly levelled, the enclosure assembly starts by placing 
the first bottom plate in its final position. Check that the plate is properly levelled by means of 
a hose level. 
If the enclosure consists of more than one module, insert a 20 x 10 mm adhesive rubber strip 
(

reference 090006-33

) in the joint between the different bottom plates.

Great care should be taken when installing this strip, since the sealing of the Transformer 
Substation depends on it.
