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. 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. 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
Any further mounting data required can be taken from the product
drawing or Section chapter 4.1 Connecting the mechanical system.

4. CONNECTION AND START-UP
4.1 Connecting the mechanical system
CAUTION
Cutting and crushing hazard when removing the device
from the packaging
Blades can be bent
→ Carefully remove the device from its packaging, only
touching the wall ring. Make sure to avoid any shock.
→ Wear safety shoes and cut-resistant safety gloves.
CAUTION
The blades of the impeller could be damaged.
→ Set down the fan carefully on a soft surface. Make sure the
blades are not subjected to load.
→ After installation, make sure the impeller moves easily
and that the blades of the impeller are not deformed or bent
and do not catch anywhere.
NOTE
Damage to device from vibration
Bearing damage, reduced service life
→ Forces or impermissibly high vibration levels must not be
transmitted to the fan from system components.
→ If the fan is connected to air ducts, it should isolated from
vibrations, for example using compensators or similar
elements.
→ Fasten the fan to the substructure without distorting it.
;
Check the device for transport damage. Damaged devices must no
longer be installed.
;
Install the undamaged device according to your application.
CAUTION
Possibility of damage to the device
Serious damage may result if the device slips during assembly.
→ Keep the device fixed in position at the installation location
until all attachment screws have been tightened.
●
The fan must not be strained on fastening.
4.2 Connecting the electrical system
CAUTION
Electrical voltage
The fan is a built-in component and features no electrically
isolating switch.
→ Only connect the fan to circuits that can be switched off with
an all-pole separating switch.
→ When working on the fan, you must switch off the
installation/machine in which the fan is installed and secure it
from being switched on again.
NOTE
Water penetration into leads or wires
Water enters at the cable end on the customers side and can
damage the device.
→ Make sure that the cable end is connected in a dry
environment.
