Translation of the original operating instructions
CAUTION
Electric charge on capacitor after device is switched off
Electric shock, risk of injury
→ Discharge the capacitors before working on the device.
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
The motor restarts automatically when operating voltage
is applied, 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.
→ Install the externally wired thermal overload protector in
the control circuit so that following a malfunction the motor
does not switch on again automatically after cooling off.
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 motor housing
Risk of burns
→ Ensure sufficient protection against accidental contact.
1.10 Transport
NOTE
Transporting the device
→ Transport the device in its original packaging only.
→ Secure the device so it cannot slip, e.g. by using a
lashing strip.
1.11 Storage
