•   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.

Xfmefe!kpjout;

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. 

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.

2.2.6.3 Busbar installation
The busbars of adjacent transport units must be connected 
to the busbar connectors (1,Fig.11) using the parts and fixing 
elements supplied with the units. Grease the contact faces.
M12 bolts must be tightened with a torque of 70 Nm and 
M12 bolts with a torque of 40 Nm.

2.2.6.4 Bolting the earth bus sections together
The earth bus sections for the individual transport units 
must be linked together. One of the two sections to be 
bolted together is fitted with a link. This must be undone, 
passed through the opening in the partition wall and 
bolted to the two adjacent earth bar sections.Grease the 
contact faces.

2.3 Electrical connections

Using M12 bolts to fix HV cable inside switchgear. 

2.3.1 Connecting the HV cables

The terminal links of the switchpanel are fitted with the 
appropriate fixing elements (M12 bolts) for the cable lugs. 
The built-in cable support rails are adjustable. 

2.3.2 Earthing the switchpanel

Connect the earth terminal of at least one panel to the 
station earth (guide value: one terminal for five panels)
The earth terminal must be connected to the earth busbar 
in the cable termination compartment.
