This component for installation may
have several local protection classes.
This information relates to this
component’s basic design.
The final protection class is based on
the component’s intended installation and
connection.
Conformity with
standards
EN 62368-1
Approval
UL 507; CSA C22.2 No. 113
With regard to cyclic speed loads, note that the rotating parts of
the device are designed for a maximum of one million load
cycles. If you have special questions, consult ebm-papst for
support.
Information on surface quality
;
Use the device in accordance with its degree of protection.
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. 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. UV radiation
in the frequency range and the intensity of natural solar radiation has no
effect on the technical properties of the products.
3.4 Mounting data
Any further mounting data required can be taken from the product
drawing or Section Chapter 4.1 Mechanical connection.
