Operating instructions

K3G630-AP01-01

Translation of the original operating instructions

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.

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 if the hands reach or are sucked 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.

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
→ The fan is always to be transported with care and in its

original packaging. #If set down too hard or at an angle for
example, the impact can lead to bearing damage or
deformation of the frame or impeller. #It must be ensured that
the fans cannot tip over during transportation and handling.

→ Secure the fan(s) with appropriate equipment such as a

lashing strip so that nothing can slip or tip, especially when
stacking multiple fans. #Also make allowance for possible
wind forces.
