Assembly of the secondary section cover 
The secondary section cover protects the secondary section track. The installation method 
depends on the type of cover. The following two variants are available:  
●  Continuous cover band 
●  Segmented cover 
If fine dust or the like can accumulate in the spaces of the segmented cover, the use of a 
cover band is advantageous.  
 
Loss of functionality and motor wear due to contamination in the motor compartment 
Contamination in the motor compartment can cause the motor to stop functioning or cause 
wear and tear. The use of scrapers to keep the air gap free is not sufficient and therefore 
not recommended. 
•  Use suitable measures to protect the motor compartment from contamination 
independently of the use of a cover band. 
Covering long secondary section tracks with cover bands is more complicated than with 
segments.  
If the traversing distance of the axis is greater than twice the slide length, proceed as follows: 
1.  Mount the primary section under the slide. 
2.  Push the slide to one side of the traversing distance. 
3.  Mount the secondary sections on the other side up to the center of the traversing 
distance. 
4.  Mark the length of the mounted secondary sections plus the required clamping length on 
the cover band. 
5.  From the mark, slide the cover band under the primary section to the side without 
secondary sections.
