Operating instructions


Translation of the original operating instructions

In the event of failure, there is electric voltage at the
rotor and impeller
The rotor and impeller are base insulated.
→ Do not touch the rotor and impeller once they are installed.

If control voltage is applied or a speed setpoint is stored,
the motor automatically restarts, e.g. after a power failure.
Danger of injury
→ Keep out of the danger zone of the device.
→ When working on the device, switch off the mains

supply voltage and secure the latter from being switched on

→ Wait until the device stops.
→ After working on the device, remove any used tools or

other objects from the device.

1.5 Safety and protective functions

Missing safety device and non-functioning safety device
If there is no safety device, you could be seriously injured, for
example if you reach into the running device or your hands are
sucked into it.
→ Operate the device only with a fixed and isolating safety

protection and a fixed guard grille.
The guard must withstand the kinetic energy of a fan blade
detaching at maximum speed.

→ The device is a built-in component. You, the owner/

operator, are responsible for providing adequate protection for
the device.

→ Shut down the device immediately if you detect a

missing or ineffective protective feature.

1.6 Electromagnetic radiation

Interference from electromagnetic radiation is possible, e.g. in conjunction
with open and closed-loop control devices.
If unacceptable emission intensities occur when the fan is installed,
appropriate shielding measures have to be taken by the user.

Electrical or electromagnetic interferences after
integrating the device in installations on the customer's
→ Verify that the entire setup is EMC compliant.

1.7 Mechanical movement

Rotating device
Body parts that come into contact with the rotor and impeller
can be injured.
→ Secure the device against accidental contact.
→ Before working on the system/machine, wait until all

parts have come to a standstill.

Flying parts
Missing safety devices may cause balancing weights or
broken fan blades to be ejected at high speeds, causing bodily
→ Take appropriate safety measures.

Rotating device
Long hair, loose items of clothing and jewellery could become
entangled and pulled into the device. You could be injured.
→ Do not wear any loose clothing or jewellery while working

on rotating parts.

→ Protect long hair by wearing a cap.

1.8 Emission

Depending on the installation and operating conditions,
a sound pressure level greater than 70 dB(A) may arise.
Danger of noise-induced hearing loss
→ Take appropriate technical safety measures.
→ Protect operating personnel with appropriate safety

equipment, e.g. hearing protection.

→ Also observe the requirements of local agencies.

1.9 Hot surface

High temperature at the electronics enclosure
Danger of burn injuries
→ Ensure that sufficient protection against accidental contact is


1.10 Transport

Transport of fan
Injuries from slipping or falling.
→ Only transport the fan in its original packaging. # Transport

the fan "lying flat", in other words with the axis vertical.

→ Secure the fan(s) so that nothing can slip or fall, for

example using a lashing strap.

1.11 Storage

; Store the device, partially or fully assembled, in a dry and

weatherproof manner in the original packing in a clean environment.

; Protect the device from environmental impacts and dirt until the final


; We recommend storing the device for a maximum up to one year to

guarantee proper operation and longest possible service life.

; Even devices explicitly suited for outdoor use are to be stored as

described prior to being commissioned.

; Maintain the storage temperature, see

chapter 3.6 Transport and storage conditions.

; Please make sure that all screwed cable glands are fitted with

dummy plugs.
