According to EN 55022 (Class B,
household environment)
If several devices are switched in parallel on the supply side
so that the line current of the arrangement is in the range of 16-
75 A, then this arrangement conforms to IEC 61000-3-12
provided that the short-circuit power S
sc
at the connection point
of the customer system to the public power system is greater
than or equal to 120 times the rated output of the arrangement.
It is the responsibility of the installation engineer or operator/
owner of the device to ensure, if necessary after consultation
with the network operator, that this device is only connected to
a connection point with a S
sc
value that is greater than or equal
to 120 times the rated output of the arrangement.
4. CONNECTION AND STARTUP
4.1 Mechanical connection
CAUTION
Cutting and crushing hazard when removing fan from
packaging
→ Carefully remove the device from its packaging, grasping it
by only the blades near the hub. 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.
;
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.
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.
