Translation of the original operating instructions
WARNING
Terminals and connections have voltage even with a
unit that is shut off
Electric shock
→ Wait five minutes after disconnecting the voltage at all poles
before opening the device.
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
The motor restarts automatically when operating voltage
is applied, 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.
→ Insert the brought-out thermal overload protector into the
control circuit so that the cooled off motor does not switch on
independently after a fault.
1.5 Safety and protective functions
DANGER
Guard missing and guard not functioning
Without a guard there is a risk of serious injury, for instance
when reaching into the device during operation. Loose parts or
items of clothing could be drawn in.
→ The device is a built-in component. As the operator, you are
responsible for ensuring that the device is secured
adequately.# Operate the device only with a fixed protective
device and guard grille.
→ Stop the device immediately if a protective device is
found to be missing or ineffective.
1.6 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.
WARNING
Rotating device
Long hair, dangling items of clothing, jewellery and similar items
can become entangled and be pulled into the device. Risk of
injury.
→ Do not wear any loose-fitting or dangling clothing or jewellery
while working on rotating parts.
→ Protect long hair with a cap.
1.7 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.
1.8 Hot surface
CAUTION
High temperature at the motor housing
Danger of burn injuries
→ Ensure that sufficient protection against accidental contact is
provided.
