WARNING
Live terminals and connections even with device
switched off
Electric shock
→ Wait five minutes after disconnecting the voltage at all poles
before opening the device.
CAUTION
In the event of a fault, the rotor and the impeller will be
energized
The rotor and the impeller have basic insulation.
→ Do not touch the rotor and impeller once installed.
CAUTION
If control voltage or a stored speed set value is applied,
the motor will restart automatically, e.g. after a power
failure.
Risk of injury
→ Keep out of the device’s danger zone.# When working on
the device, switch off the line voltage and ensure that it
cannot be switched back on.
→ Wait until the device comes to a stop.
→ After working on the device, remove any tools or other
objects from the device.
CAUTION
The motor restarts automatically when operating voltage
is applied, e.g. after a power failure.
Risk of injury
→ Keep out of the motor's danger zone.
→ When working on the motor, switch off the line voltage
and ensure that it cannot be switched back on.
→ Wait until the motor comes to a stop.
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
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.
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.
1.9 Storage
;
