Appendix
Used protective clothing must be disposed of in accordance with the locally applicable
guidelines.
Proper disposal and appropriate recycling of this product prevents damage to the environ-
ment and dangers to your personal health.
NOTICE
Disposal in domestic waste is forbidden!
In the European Union, this symbol can appear on the product, the packaging or the ac-
companying documentation. It means that the electrical and electronic products in ques-
tion must not be disposed of along with domestic waste.
To ensure proper handling, recycling and disposal of the used products in question, please
note the following points:
ƒ
Only hand over these products at designated, certified collecting points.
ƒ
Observe the locally applicable regulations!
Please consult your local municipality, the nearest waste disposal site, or the dealer who sold
the product to you for information on proper disposal. For further information on recycling,

If a Nord-Lock screw locking device is used, then increase the tightening torque by 10 %!
The motor in series design (conforming to IEC 60034‑17) can be operated with a frequency
converter. Contact customer service if the rated voltage is above 415 V/50 Hz or
480 V/60 Hz. Because of the additional heating caused by harmonics, the rated power of the
motor should be around 10 % more than the power requirement of the mixer. For frequency
converters with a low-harmonic output, it is possible to reduce the 10 % power reserve.
Harmonic waves are reduced by means of output filters. Synchronize the frequency con-
verter and the filter with each other!
The configuration of the frequency converter depends on the rated motor current. Make
sure that the mixer operates across the entire control range without jerking or vibrating
(without vibrations, resonance, oscillation). Otherwise, the mechanical seals may leak or be
damaged. Increased motor noise caused by the harmonics of the power supply is normal.
During parameterisation of the frequency converter, observe the setting of the quadratic
curve (U/f curve) for submersible motors! The U/f curve ensures that the output voltage at
