Operating instructions

K3G280-RU26-81

Translation of the original operating instructions

1.4 Voltage

;

Check the device's electrical equipment at regular intervals; see
Chapter 5.2 Safety inspection.

;

Replace loose connections and defective cables immediately.

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
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
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.

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 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.

1.11 Storage

;

Store the device, partially or fully assembled, in a dry place,
protected against the weather and free from vibration, 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.
