Operating instructions
1.7 Mechanical movement
DANGER
Rotating device
Body parts that come into contact with the rotor and impeller
can be injured.
→ Secure the device against accidental contact.
→ Before working on the system/machine, wait until all
parts have come to a standstill.
WARNING
Rotating device
Long hair, dangling items of clothing, jewellery and similar items
can become entangled and be pulled into the device. Risk of
injury.
→ Do not wear any loose-fitting or dangling clothing or jewellery
while working on rotating parts.# Protect long hair with a cap.
WARNING
Terminals and connections have voltage even with a
unit that is shut off
Electric shock
→ Wait five minutes after disconnecting the voltage at all poles
before opening the device.
CAUTION
In the event of failure, there is electric voltage at the
rotor and impeller
The rotor and impeller are base insulated.
→ Do not touch the rotor and impeller once they are installed.
CAUTION
If control voltage is applied or a speed setpoint is stored,
the motor will restart automatically, e.g. after a mains
failure.
Risk of injury
→ Keep out of the device hazard zone.# When working on the
device, switch off the mains power and ensure that it cannot
be switched back on.
→ Wait until the device stops.
→ After working on the device, remove any tools used or
other objects from the device.
1.8 Emission
WARNING
Depending on the installation and operating conditions,
a sound pressure level greater than 70 dB(A) may arise.
Danger of noise-induced hearing loss
→ Take appropriate technical safety measures.
→ Protect operating personnel with appropriate safety
equipment, e.g. hearing protection.
→ Also observe the requirements of local agencies.
1.5 Safety and protective functions
DANGER
Protective device missing and protective device not
functioning
Without a protective device there is a risk of serious injury, for
instance when reaching into the device during operation.
→ Operate the device only with a fixed protective device and
guard grille.# The fixed protective device must be able to
withstand the kinetic energy of a fan blade that becomes
detached at maximum speed. There must not be any gaps
which it is possible to reach into with the fingers, for example.
→ The device is a built-in component. As the operator, you
are responsible for ensuring that the device is secured
adequately.
→ Stop the device immediately if a protective device is
found to be missing or ineffective.
1.9 Hot surface
CAUTION
High temperature at the electronics housing
Risk of burns
→ Ensure sufficient contact protection.
1.10 Transport
NOTE
Transporting the device
→ Transport the device in its original packaging only.
Translation of the original operating instructions
1.11 Storage
;
Store the device, partially or fully assembled, in the original
packaging in a clean, dry and weatherproof place free of vibrations.
;
Protect the device against environmental effects and dirt until final
installation.
;
We recommend storing the device for no longer than one year in
order to guarantee trouble-free operation and longest possible service
life.
;
Even devices explicitly intended for outdoor use are to be stored as
described prior to commissioning.
;
Maintain the storage temperature, see
chapter 3.5 Transport and storage conditions.
1.6 Electromagnetic radiation
Interference from electromagnetic radiation is possible, e.g. in conjunction
with open and closed-loop control devices.
If unacceptable emission intensities occur when the fan is installed,
appropriate shielding measures have to be taken by the user.
NOTE
Electrical or electromagnetic interferences after
integrating the device in installations on the customer's
side.
→ Verify that the entire setup is EMC compliant.

The surfaces of the products conform to the generally applicable industrial
standard. The surface quality may vary during the production period.
Strength, dimensional stability and dimensional accuracy are not affected
by this.
The colour pigments of the paints used react perceptibly to UV light over
the course of time. This does not however have any influence on the
technical properties of the products. To prevent the formation of patches
and fading, the product is to be protected against UV radiation. Changes
in colour are not a reason for complaint and are not covered by the
warranty.
