3.6 Electromagnetic compatibility
EMC regulations
according to EN 50121-3-2
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
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.
→ 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.
;
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.
