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.
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.
→ 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
substructure.
;
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.
