Protection class
assignment
I; If a protective earth is connected by
the customer
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 15085-1, CPC3; EN 45545-2, HL3;
EN 50155; EN 61373, Cat. 1B

Comment
If voltage (e.g. 230 VAC) is passed
through the alarm relay, the SELV signal
wires lose their property of reinforced
insulation, meaning they then have only
basic insulation
The SELV property (reinforced
insulation) is not lost when voltages of up
to 110 VDC are passed through the
alarm relay.
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.
;
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. 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
Further mounting data can be taken from the product drawing or Chapter
4.1 Mechanical connection as required.
