1.5 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.
1.6 Mechanical movement
WARNING

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.
WARNING
Ejected parts
If the motor is operated with attached fan blades, missing
protective devices may allow balancing weights or broken fan
blades to be ejected and cause injuries.
→ Take appropriate safety measures such as installing guard
grilles.
→ Keep out of the exhaust zone.
1.7 Hot surface
CAUTION
High temperature on electronics housing
Risk of burns
→ Ensure sufficient protection against accidental contact.
1.8 Transport
CAUTION
Transporting the motor
Crushing hazard
→ Wear safety shoes and cut-resistant safety gloves.
→ Transport the motor in its original packaging only.
→ Secure the device so it cannot slip, e.g. by using a
lashing strip.
