4. CONNECTION AND STARTUP
4.1 Mechanical connection
CAUTION
Cutting and crushing hazard when removing device
from packaging
Blades can bend
→ Carefully remove the device from its packaging, by the fan
housing. Strictly avoid shocks.
→ Wear safety shoes and cut-resistant safety gloves.
NOTE
Damage to the device from vibration
Bearing damage, shorter service life
→ The fan must not be subjected to force or excessive vibration
from sections of the installation. #It is advisable to use spring
or rubber isolators for decoupling (not included in scope of
delivery). The fan is to be operated sufficiently far away from
the resonant frequency of the vibration isolators. #If the fan is
connected to air ducts, the connection should be isolated
from vibration, e.g. using compensators or similar elements.
→ Ensure stress-free attachment of the fan to the sub-structure.
;
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.
