Operating instructions
W3G350-CN01-32
Translation of the original operating instructions
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 power
failure.
Risk of injury
→ Keep out of the device danger zone.# When working on the
device, switch off the mains power and ensure that it cannot
be switched back on.
→ After working on the device, remove any tools used or
other objects from the device.
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 if the hands reach or are sucked 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.
1.6 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.
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.
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.
1.9 Hot surface
CAUTION
High temperature at the electronics housing
Risk of burns
→ Ensure sufficient contact protection.

weatherproof manner in the original packing in a clean environment.
;
Protect the device from environmental impacts and dirt until the final
installation.
;
We recommend storing the device for a maximum up to one year to
guarantee proper operation and longest possible service life.
;
Even devices explicitly suited for outdoor use are to be stored as
described prior to being commissioned.
;
Maintain the storage temperature, see
chapter 3.6 Transport and storage conditions.
