objects from the device.
1.5 Safety and protective features
DANGER
Guard missing and guard not functioning
Without a guard, hands may become caught up in the device
during operation for example, resulting in serious injury. Loose
parts or items of clothing could be drawn in.
→ The device is a built-in component. As the owner, you are
responsible for ensuring that the device is adequately
safeguarded.# Operate the device only with a fixed
protective device and guard grill.
→ Stop the device immediately if a protective device is
found to be missing or ineffective.
WARNING
Damage to guard grill, parts flying out
The guard grill is not suitable for heavy loads. Parts lying on the
guard grill or falling through the guard grill may be thrown out by
the fan when in operation.
→ Never step on the guard grill or subject the guard grill to load.
→ Do not place any objects on the guard grill.
→ There must be sufficient space around the fan to be able
to get past the fan.
1.6 Electromagnetic radiation
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 have to 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
DANGER
Rotating device
Risk of injury to body parts coming into contact with the rotor or
the impeller.
→ Secure the device against accidental contact.
→ Before working on the system/machine, wait until all
parts have come to a standstill.
DANGER
Ejected parts
Missing protective devices may cause balancing weights or
broken fan blades to be ejected and cause injuries.
→ Take appropriate safety measures.
WARNING
Rotating device
Long hair and dangling items of clothing, jewelry and the like
can become entangled and be pulled into the device. Injuries
can result.
→ Do not wear any loose-fitting or dangling clothing or jewelry
while working on rotating parts.
→ Protect long hair with a cap.
1.8 Emissions
WARNING
Depending on the installation and operating conditions,
the sound pressure level may exceed 70 dB(A).
Risk of noise-induced hearing loss
→ Take appropriate technical safety measures.
→ Protect operating personnel with appropriate safety
equipment such as hearing protection.
→ Also observe the requirements of local agencies.
1.9 Hot surface
CAUTION
High temperature on electronics housing
Risk of burns
→ Ensure sufficient protection against accidental contact.
1.10 Transport
WARNING
Transporting the fan
Injuries from tipping or slipping
→ Wear safety shoes and cut-resistant safety gloves.
→ The fan is only to be transported in its original packaging.
