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 automatically restarts, e.g. after a power failure.
Danger of injury
→ Keep out of the danger zone of the device.
→ When working on the device, switch off the mains
supply voltage and secure the latter from being switched on
again.
→ Wait until the device stops.
→ After working on the device, remove any used tools or
other objects from the device.
1.5 Safety and protective functions
DANGER
Missing safety device and non-functioning safety device
If there is no safety device, you could be seriously injured, for
example by reaching into the running device with your hands.
→ Operate the device only with a fixed and isolating safety
protection and a fixed guard grille. The guard must withstand
the kinetic energy of a fan blade detaching at maximum
speed.
→ The device is a built-in component. You, the owner/
operator, are responsible for providing adequate protection for
the device.
→ Shut down the device immediately if you detect a
missing or ineffective protective feature.
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, loose items of clothing and jewellery could become
entangled and pulled into the device. You could be injured.
