4. CONNECTION AND START-UP
4.1 Connecting the mechanical system
CAUTION
Cutting and crushing hazard when removing the fan
from the packaging
→ Carefully remove the device from its packaging, only
touching the guard grille. Make sure to avoid any shock.
→ Wear safety shoes and cut-resistant safety gloves.
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
