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.
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.
CAUTION
The blades of the impeller could be damaged.
→ Carefully set down the fan on a soft surface. Make sure the
blades are not subjected to load.
→ Following installation, make sure the impeller moves
easily and that the blades of the impeller are not deformed or
bent and do not catch at any point.
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.
;
Check the device for transport damage. Damaged devices are not to
be installed.
;
Install the undamaged device in accordance with your application.
;
Do not perform any modifications, additions or conversions on the
device. Replacing the terminal box is not permitted.
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.
CAUTION
Voltage
The fan is a built-in component and has no disconnecting switch.
→ Only connect the fan to circuits that can be switched off with
an all-pole disconnection switch.
→ When working on the fan, secure the system/machine in
which the fan is installed so as to prevent it from being
switched back on.
NOTE
Water ingress into wires or cables
Water ingress at the customer end of the cable can damage the
device.
→ Make sure the end of the cable is connected in a dry
environment.
Only connect the device to circuits that can be switched off with
an all-pole disconnection switch.
