Use the device in accordance with its degree of protection.
Information on surface quality
The surfaces of the products conform to the generally applicable industrial
standard. The surface quality may change during the production period.
This has no effect on strength, dimensional stability and dimensional
accuracy.
The color pigments in the paints used perceptibly react to UV light over
the course of time. This does not however in any way affect the
technical properties of the products. The product is to be protected against
UV radiation to prevent the formation of patches and fading. Changes in
color are not a reason for complaint and are not covered by the warranty.
3.4 Mounting data
For screw clearance, see Chapter 3.1 Product drawing
Strength class of
screws

;
Secure the screws against unintentional loosening (e.g. use self-
locking screws).
Any further mounting data required can be taken from the product
drawing or Section Chapter 4.1 Mechanical connection.
