Guidelines
Declaration of Conformity
A conformity evaluation for the applicable EU directives has been carried out for this product. The conformity evaluation is set out in writing
in a separate document and can be requested if required. It is forbidden to start use of the product until the machine or system into which
it should be built is operating in accordance with all applicable EU directives.
Without a conformity evaluation, this product is not suitable for use in areas where there is a high danger of explosion. This statement is
based on the ATEX directive.
Guidelines for Electromagnetic Compatibility (EMC)
In accordance with the EMC directives 89/336/EEC, the
individual components produce no emissions. However,
functional components e.g. rectifiers, phase demodulators,
ROBA
®
-switch devices or similar controls for mains-side
energisation of the brakes 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
The catalogue values are standards which can, in certain cases,
vary. When dimensioning the brakes, please remember that
installation situations, braking 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 brake at the place of
installation.
The brakes are designed for a relative duty cycle of 100 %.
The brakes are only designed for dry running. The braking
torque is lost if the friction surfaces come into contact with oil,
grease, water or similar substances.
The braking torque is dependent on the present run-in
condition of the brakes.
Manufacturer-side corrosion protection of the metallic
surface is provided.
Without a conformity inspection, this product is not suitable
for use in areas where there is a high danger of explosion.
This statement is based on the directive 94/9/EC (ATEX
directive). Please contact the manufacturer separately for
brakes in ATEX-design!

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. Should the basic insulation fail, the contact voltage
cannot function (VDE 0580).
Protection (mechanical) IP54
When installed, protected against dust, contact and splashing
water from all directions (dependent on customer-side
mounting arrangements).
Protection (electrical) IP54
Dust-proof and protected against contact as well as against
splashing water from all directions.
Protection IP65 (Type 891._ _ _.1)
Dust-proof and protected against contact as well as against jet
water from all directions.
Ambient Temperature -0 °C up to +40 °C
At temperatures of around or under freezing point, condensation
can strongly reduce the torque, or the rotors can freeze up. The
user is responsible for taking appropriate countermeasures.
Insulation Material Class F (+155 °C)
The magnetic coil and the casting compound are suitable for
use up to a max. operating temperature of +155 °C.
