specific questions, contact ebm-papst for support.
;
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. This does not however have any influence on the
technical properties of the products. 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.
3.4 Mounting data
Any further mounting data required can be taken from the product
drawing or Section chapter 4.1 Connecting the mechanical system.

For depth of screw, see chapter 3.1 Product drawing
;
Secure the mounting screws against accidentally coming loose (e.g.
by using self-locking screws).
