Operating instructions
G1G170-AB05-81
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 by reaching into the running device with your hands.
→ 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.
→ Instantly stop the device once 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.
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
Danger of injury from open blower
Gas escapes. When the blower is open, you come into contact
with rotating and electrically live parts. Escaping gas may also
cause explosions.
→ Never open the blower.
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.
WARNING
Flying parts
Missing safety devices may cause fan blades to be ejected at
high speeds, causing bodily harm.
→ Take appropriate safety measures.
The safety devices must prevent contact with rotating parts
and the printed circuit board.
1.8 Deflagration
DANGER
Gas escapes through leaky housing after deflagration
Danger of injury
→ After a deflagration, check that the housing of the gas blower
is tightly sealed.
→ Replace any gas blower with a leaky housing.
DANGER
Fire and deflagration hazard
The gas blower is not approved according to Ex protection
guidelines. Rotating parts can scrape against stationary parts.
This may cause sparks and chips. The surface temperature
may rise, resulting in a fire.
→ Check which hazards arise from installing, operating,
servicing or disposing the gas blower in conjunction with
your device.
Prevent these hazards.
Carry out all appropriate measures to this purpose.
1.9 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.
1.10 Hot surface
CAUTION
High temperature at the electronics enclosure
Danger of burn injuries
→ Ensure that sufficient protection against accidental contact is
provided.
1.11 Transport
NOTE
Transport of blower
→ Transport the blower in its original packaging only.
→ Secure the blower so that it does not slip, e.g. by using a
clamping strap.
