When connecting the power cable to the mains supply, use an external fusethat complies with
the regulations applicable to the place of installation .
•Please check the type plate for details on the necessary voltage and
frequency for the device.
•Make sure the levels agree with the existing mains power supply.
•Use the supplied connection cable to connect the device to the mains power
supply.
•Make sure that the voltage and frequency of your mains connection
corresponds to that on the type plate.
–The mains connection must be fused to at least 16A.
–An electrical connection without protective earth PE is not permitted.
The drive of the device is equipped with a frequency converter. In order to satisfy the EMC
Directive, this is fitted with a mains filter and shielded cables to the motor. If your mains
connection includes a residual current protection device, the suppressor capacitor wiring of the
frequency converter when this is switched on (it is switched on by closing the grinding chamber
hood) can lead to accidental triggering of the residual current protection device without any error
being present on the device or in the mains installation.
In accordance with the state of the art, selective all current sensitive residual current protection
devices are recommended for such cases. The tripping current must be sufficiently
dimensioned because capacitive compensating current (shielded cable, mains filter) which only
occurs for a short time can easily lead to accidental triggering.
In certain circumstances, it may be necessary to operate the device without a residual current
protection device. It is then necessary, however, to check that this does not contravene the
local regulations of the electricity company or other institutions and the applicable standards.
3.8 Creating interface connection

•Inactive interface (SC) for optional data communication with an external
device. This requires updating of the software.
NOTICE
The interface cable must not be longer than 2.5m. Longer cables can lead to faults in data
transmission.

CAUTION
Danger of personal injury
Dangerous nature of the sample
–Depending on the dangerous nature of your sample, take the
necessary measures to rule out any danger to persons.
•Observe the safety guidelines and datasheets of your
sample material.
Target group: Operator, All persons concerned with the machine in any form.
Machine type designation: RS200
The RS200 vibratory disc mill is used for the fast, loss-free and reproducible pulverisation of
medium hard, hard, brittle and fibrous materials to analytical fineness. Thanks to the novel
Stabilized Plane Drive, the mill runs smoothly and safely, also with heavy grinding sets and at
maximum speed.
The vibratory disc mill is used successfully in almost all areas of industry and research. This
applies in particular where there are high demands in terms of hygiene, speed, fineness and
reproducibility.
The RS200 is particularly suitable for preparing samples for spectral analysis because it
achieves high degrees of final fineness in the shortest time.
Due to its robust design, the RS200 has proven to be especially good in the construction
materials sector (cement), in geology, mineralogy, metallurgy and in power plants.
Soil, concrete, electronic components, ores, glass, ceramics, coal, coke, corundum, metal
oxide, minerals, plant parts, slag, silicates, cement, cement clinker and many other substances
can be ground easily, fast and without loss.
Advantages
–Reproducible grinding results using the "Stabilized Plane Drive" (prevents
tumbling of the grinding set)
–Variable speed 700 –1,500min-1
–Extremely short grinding duration
–Agate and tungsten carbide recognition for automatic speed reduction
–10 standard operating procedures can be saved
–No sample loss thanks to optimal O-ring seal
–Wide choice of materials for neutral-to-analysis grinding
–Closed, noise insulated grinding chamber
–Grinding jar quick release
–Slide-in system for the ergonomic insertion of the grinding jars
–Automatic lid closing
NOTICE
Area of use of the machine
–This machine is a laboratory machine designed for 8-hour single-shift
operation.
•This machine may not be used as a production machine nor is it
intended for continuous operation.

Wear or damage to the grinding set
No filling or insufficient filling quantity
–Increased wear or damage to the grinding set is possible if the grinding set
is operated without filling or with insufficient filling qantity.
•The grinding set must be filled to at least 1/3 of the nominal volume.
4.3 Feed Grain Size
In addition to the instrument settings, the filling level of the grinding jar is also of crucial
importance for a successful grinding process in the Vibratory Disc Mill of Retsch GmbH. The
table indicates approximate values for the recommended amount of sample as a function of the
grinding set used. A median filling (sample quantity) results in best grinding efficiency and
increases the life time of the grinding sets.
