Translation of the original operating instructions
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.
3.5 Mounting data
Further mounting data can be taken from the product drawing or Chapter
4.1 Mechanical connection as required.
Strength class of
screws

For screw clearance, see Chapter 3.1 Product drawing
;
Secure the screws against unintentional loosening (e.g. use self-
locking screws).
3.6 Transport and storage conditions
Max. permitted
ambient temp. for
motor (transport/
storage)
+80 °C
Min. permitted
ambient temp. for
motor (transport/
storage)
-40 °C
3.7 Electromagnetic compatibility
EMC regulations
according to EN 50121-3-2
If several devices are switched in parallel on the supply side
so that the line current of the arrangement is in the range of 16-
75 A, then this arrangement conforms to IEC 61000-3-12
provided that the short-circuit power S
sc
at the connection point
of the customer system to the public power system is greater
than or equal to 120 times the rated output of the arrangement.
It is the responsibility of the installation engineer or operator/
owner of the device to ensure, if necessary after consultation
with the network operator, that this device is only connected to
a connection point with a S
sc
value that is greater than or equal
to 120 times the rated output of the arrangement.
4. CONNECTION AND STARTUP
4.1 Mechanical connection
CAUTION
Risk of cutting and crushing when removing device
from packaging
→ Carefully remove the device from the packaging by grasping
hold of the frame. Never subject to any impact.
→ Wear safety shoes and cut-resistant safety gloves.
CAUTION
Heavy load when unpacking device
Risk of physical injury, such as back injuries.
→ Two people should work together to remove the device from
its packaging.
;
The fan may not be handled in the area around the inlet nozzle during
transport and installation.
There is a risk of damage to the impeller.
;
Check the device for transport damage. Damaged devices are not to
be installed.
;
Install the undamaged device in accordance with your application.
CAUTION
Possible damage to the device
If the device slips during installation, serious damage can result.
→ Ensure that the device is securely positioned at its place of
installation until all fastening screws have been tightened.
●
The fan must not be strained on fastening.
4.2 Electrical connection
DANGER
Voltage on the device
Electric shock
→ Always connect a protective earth first.
→ Check the protective earth.
DANGER
Faulty insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation
regulations for voltage, current, insulation material, capacity,
etc.
→ Route cables so that they cannot be touched by any
rotating parts.
DANGER
Electrical charge (>50 µC) between phase conductor and
protective earth connection after switching off supply
with multiple devices connected in parallel.
Electric shock, risk of injury
→ Ensure sufficient protection against accidental contact.
Before working on the electrical hookup, short the supply
and PE connections.
