Operating instructions
G1G126-AA49-71
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 when reaching 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
Danger of injury from open blower
Escaping gas. When the blower is open, you come into contact
with rotating and electrically live parts. Escaping gas can also
cause explosions.
→ Never open the blower.
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.
WARNING
Ejected parts
Missing protective devices may allow fan blades to be ejected
and cause injuries.
→ Take appropriate safety measures.
The protective devices must prevent contact with rotating
parts and the circuit board.
1.8 Deflagration
DANGER
Gas escaping through leaky housing after deflagration
Risk of injury
→ After a deflagration, verify that the gas blower's housing is
sealed.
→ Replace any gas blower that has a leaky housing.
DANGER
Fire and deflagration hazard
The gas blower is not approved according to the explosion
protection directives. Rotating parts can scrape against
stationary parts. This can lead to sparking and chipping. The
surface temperature can rise, resulting in a fire.
→ Check which hazards arise from installing, operating,
servicing or disposing of the gas blower in conjunction with
your device.
Avoid any such hazards.
Carry out all necessary measures.
1.9 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.
