Comment
A prerequisite for operation is a Class 1
vehicle electrical system architecture
according to EN 50533; if supply
potential (e.g. 230 VAC) is passed
through the alarm relay, the SELV signal
wires lose their property of reinforced
insulation and 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.
