Use the device in accordance with its protection type.
Notes on surface quality
The surfaces of the products conform to the generally applicable industrial
standard. The surface quality may vary during the production period.
Strength, dimensional stability and dimensional accuracy are not affected
by this.
The colour pigments of the paints used react perceptibly to UV light over
the course of time. To prevent the formation of patches and fading, the
product is to be protected against UV radiation. Changes in colour are
not a reason for complaint and are not covered by the warranty. UV
radiation in the frequency range and the intensity of natural solar radiation
has no effect on the technical properties of the products.
