Safety Regulations
These Safety Regulations are user hints only and may not be complete!
Danger!
Danger of death! Do not touch voltage-
carrying cables and components.
To prevent injury or damage, only professionals and
specialists should work on the devices.
Danger!
This warning applies if:
the electromagnetic clutch is used incorrectly.
the electromagnetic clutch is modified.
the relevant standards for safety and / or installation
conditions are ignored.
Warning!
Before product installation and initial
operation, please read the Installation and
Operational Instructions carefully and
observe the Safety Regulations. Incorrect operation can
cause injury or damage. The electromagnetic clutches have
been developed in accordance with the latest technology
regulations and are, at the point of delivery, operationally
safe.
Please Observe!
Only specialists who are trained in the transport,
installation, operation, maintenance and general operation
of these devices and who are aware of the relevant
standards should be allowed to carry out this work.
Technical data and specifications (Type tags and
documentation) must be followed.
The correct connection voltage must be connected
according to the Type tag.
Never loosen electrical connections or carry out
installations, maintenance or repairs while the voltage
connection is energised!
Cable connections must not be placed under mechanical
strain.
Check electrical components for signs of damage before
putting them into operation. Never bring them into contact
with water or other fluids.
The torque is lost if the friction linings come into contact
with oil or grease.
Appointed Use
ROBATIC
®
-clutches are for use in machines and systems and
must only be used in the situations for which they are ordered
and confirmed.
Using them for any other purpose is not allowed!
Guidelines for Electromagnetic Compatibility
(EMC)
In accordance with the EMC directives 89/336/EEC, the
individual components produce no emissions. However,
functional components for mains-side energisation of the
clutches, e.g. rectifiers, phase demodulators, ROBA
®
-switch
devices or similar controls, can produce disturbance which lies
above the allowed limit values.
For this reason it is important to read the Installation and
Operational Instructions very carefully and to keep to the EMC
directives.
Device Conditions
Please Observe!
The catalogue values are standards which
can, in certain cases, vary. When
dimensioning the clutches, please
remember that installation situations, torque fluctuations,
permitted friction work, run-in behaviour and wear as well as
general ambient conditions can all affect the given values.
These factors should therefore be carefully assessed, and
alignments made accordingly.
Please Observe!
Mounting dimensions and connecting dimensions must be
adjusted according to the size of the clutch at the place of
installation.
The clutches are designed for a relative duty cycle of
100 %.
The clutches are only designed for dry running.
The torque is lost if the friction surfaces come into contact
with oil, grease, water or similar substances.
The torque is dependent on the present run-in condition of
the clutches.
Manufacturer-side corrosion protection of the metallic
surface is provided.
Protection Class I
This protection can only be guaranteed if the basic insulation is
intact and if all conductive parts are connected to the PE
conductor on the permanent installation. Should the basic
insulation fail, the contact voltage cannot remain (VDE 0580).
Protection (electrical) IP 54:
Dust-proof and protected against contact as well as against
splashing water from all directions.
Valid for coil, casting compound and connection strands.
Ambient Temperature –20 °C up to +40 °C
Warning!
At temperatures of around or under freezing point, condensation
can strongly reduce the torque. During longer downtimes, the
friction surfaces can stick. The user is responsible for taking
appropriate counter measures.
Insulation Material Class F (+155 °C)
The magnetic coil and the casting compound are suitable for use
up to a maximum operating temperature of +155 °C.
