1.5 Safety and protective features
13. 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 with a fixed and insulating safety device as well as a secured protective net, if the
unit is free-blowing or free-suctioning and is not connected to ducts. The protective net must be able
to withstand the kinetic energy of an impeller part. The unit is a built-in component. You, the owner is
responsible for providing adequate protection for the unit. Stop the device immediately if you detect a
missing or ineffective safety device.
1.6 Electromagnetic radiation
14. Interference from electromagnetic radiation is possible, e.g. in conjunction with open- and closed-loop
control devices.
If impermissible radiation levels occur following installation, appropriate shielding measures must be
taken by the user.
NOTE
Electrical or electromagnetic interference after installing the device in customer equipment.
Verify that the entire setup is EMC-compliant.
1.7 Mechanical movement
15. DANGER
Rotation device
Risk of injury to body parts coming into contact with the rotor or the impeller.
Pay special attention to this if the unit is expected to be started without any associated ducting or
safety devices.
Secure the device against accidental contact.
Before working on the system/machine, wait until all parts have come to a standstill.
