CAUTION
In the event of fault, electric voltage is present at the rotor
and impeller
The rotor and impeller are base insulated.
Do not touch the rotor and impeller when 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.
If the leakage current of the device is greater than 3.5 mA, a perma-
nent earth wire connection is required. The device can be earthed
using two earth wires with a respective outer conductor cross-sec-
tion or one earth wire with at least 10 mm.
1.5 Safety and protective functions
DANGER
Missing safety device and non-functioning protective features
If there is no safety device, you could be seriously injured, for exam-
ple by reaching into the running device with your hands.
Operate the device only with a fixed guard and guard grille.
The guard must withstand the kinetic energy of a fan blade.
The device is a built-in component that has no function on its
own. As the operator, you are responsible for ensuring that the
device is adequately secured.
Shut down the device immediately if you detect a missing or inef-
fective protective feature.
1.6 Electromagnetic radiation
Interference from electromagnetic radiation possible, e.g. in conjunction with open
and closed-loop control devices.
If unacceptable emission intensities occur when the fan is installed, suitable shiel-
ding measures must be taken before the device is commissioned.
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 unit to prevent contact. Before working on the installa-
tion/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.
Do not wear any loose clothing or jewellery while working
on moving parts.
Protect long hair with a hood.
1.8 Emission
WARNING
Depending on the installation and operating conditions, a sound
pressure level greater than 70 dB(A) can arise.
Danger of noise-induced hearing loss
Take appropriate technical safety measures.
Safeguard the operating personnel with appropriate protection
measures, e.g. ear protectors.
1.9 Hot surface
CAUTION
High temperature at the electronics enclosure
Danger of burn injuries
Ensure that sufficient protection against accidental contact
is provided.
1.10 Transport
CAUTION
Transport of fan
Transport the fan in its original packaging only.
Secure the fan so that it does not slip, for example using a las-
hing strap.
1.11 Storage
Store the device in a dry and 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 of one year.
Maintain the storage temperature.
1.12 Disposal
When disposing of the device, please comply with all relevant requirements and
regulations applicable in your country.
