Translation of the original operating instructions
CAUTION
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.
CAUTION
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
again.
→ 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
DANGER
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
NOTE
Electrical or electromagnetic interferences after
integrating the device in installations on the customer's
side.
→ Verify that the entire setup is EMC compliant.
1.7 Mechanical movement
DANGER
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.
DANGER
Flying parts
Missing safety devices may cause balancing weights or
broken fan blades to be ejected at high speeds, causing bodily
harm.
→ Take appropriate safety measures.
WARNING
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
WARNING
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
CAUTION
High temperature at the electronics enclosure
Danger of burn injuries
→ Ensure that sufficient protection against accidental contact is
provided.
1.10 Transport
WARNING
Transport of fan
Injuries from slipping or falling.
→ Only transport the fan in its original packaging.
→ The fans must always be transported and handled such
that they cannot tip.
→ Transport the fan "upright", in other words with the axis
horizontal.
→ Secure the fan(s) with a lashing strap, for example, so
that nothing slips or tips; this is especially important if
stacking multiple fans.
→ Also take into consideration potential wind forces.
1.11 Storage
WARNING
Storing the fan
Injuries from slipping or falling.
→ The fans must always be stored and handled such that they
cannot tip.
→ Secure the fan(s) with a lashing strap, for example, so
that nothing slips or tips; this is especially important if
stacking multiple fans.
→ Also take into consideration potential wind forces.
;
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
installation.
;
We recommend storing the device for a maximum up to one year to
guarantee proper operation and longest possible service life.
