Operating instructions
W4E450-CU03-02
Translation of the original operating instructions
→ 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
The motor restarts automatically when operating voltage
is applied, 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.
1.5 Safety and protective features
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 only with a fixed protective device and
guard grille.
→ The fixed protective device must be able to withstand the
kinetic energy of a fan blade that becomes detached at
maximum speed. There must not be any gaps which it is
possible to reach into with the fingers, for example.
→ The device is a built-in component. As the operator, you
are responsible for ensuring that the device is secured
adequately.
→ Stop the device immediately if you notice a missing or
ineffective protective device.
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.
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 motor housing
Risk of burns
→ Ensure sufficient protection against accidental contact.
1.10 Transport
NOTE
Transporting the device
→ Transport the device in its original packaging only.
→ Secure the device so it cannot slip, e.g. by using a
lashing strip.
1.11 Storage
;
Store the device, partially or fully assembled, in a dry and
weatherproof manner in the original packaging in a clean environment.
;
Protect the device against environmental effects and dirt until final
installation.
;
We recommend storing the device for no longer than one year in
order to guarantee trouble-free operation and the longest possible
service life.
;
Even devices explicitly intended for outdoor use are to be stored as
described prior to commissioning.
;
Maintain the storage temperature, see
Chapter 3.6 Transport and storage conditions.
;
Make sure that all cable glands are fitted with dummy plugs.
