• At the joint of the transport units to be bolted together,
pass the fixing bolts through the frame of the left-hand
panel (viewed to operating front) and through the
partition and screw them into the frame of the
right-hand panel. The associated nuts are fixed by
pressure in the support structure of the right-hand
panel so that they cannot be lost.
• Check to see whether the bolted panels are truly vertical.
• Move up the other transport units one after the other,
align them and bolt the support structures together.

2.2.6.2 Fixing the switchpanels to the foundations

Refer to the examples given in Fig.10. The baseframes of
the double panels have three 45mm×25mm cutouts for
fixing purposes.
Weld the baseframes of the panels in the 45mm×25mm
cutouts to the foundation rails. Use shims (Section 2.2.6.1)
where necessary to avoid welding across air gaps.
Coat the welds with anti-corrosion paint.

Fig.10 Fixing the switchpanels to the foundations
Bolted connections:
Bolt the panels to the foundation rails (false floor) through
the 45mm×25mm cutouts. Insert shims between the
foundation and the baseframe in the cutout section.
Tighten the bolts without distorting the switchpanels. At
locations where no foundation rails can be embedded. The
switchpanels are placed direct onto the reinforced concrete
floor and fixed with dowels.
