Safety Regulations
These Safety Regulations are user hints only and may not be complete!
General Guidelines
DANGER
Danger of death!
Do not touch voltage-carrying lines and
components.
Brakes may generate further risks, among other things:
Hand injuries Danger of
seizure
Contact with
hot surfaces
Magnetic
fields
Severe injury to people and damage to objects may result if:

the electromagnetic brake is used incorrectly.

the electromagnetic brake is modified.

the relevant standards for safety and / or installation
conditions are ignored.
During the risk assessment required when designing the machine
or system, the dangers involved must be evaluated and removed
by taking appropriate protective measures.
To prevent injury or damage, only specialist personnel are
allowed to work on the components.
They must be familiar with the dimensioning, transport,
installation, inspection of the brake equipment, initial operation,
maintenance and disposal according to the relevant standards
and regulations.
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. At the time these Installation and Operational
Instructions go to print, the electromagnetic brakes accord with
the known technical specifications and are operationally safe at
the time of delivery.

Technical data and specifications (Type tags and
documentation) must be followed.

The correct connection voltage must be connected according
to the Type tag and wiring guidelines.

Check electrical components for signs of damage before
putting them into operation. Never bring them into contact
with water or other fluids.

Please observe the EN 60204-1 requirements for electrical
connection when using in machines.
Only carry out installation, maintenance and
repairs in a de-energized, disengaged state
and secure the system against inadvertent
switch-on.
Guidelines for Electromagnetic Compatibility
(EMC)
In accordance with the EMC directive 2014/30/EU, the individual
components produce no emissions. However, functional
components e.g. mains-side energization of the brakes with
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.
Application Conditions
The catalogue values are guideline values which
have been determined in test facilities. It may be
necessary to carry out your own tests for the
intended application. When dimensioning the
brakes, please remember that installation situations, braking
torque fluctuations, permitted friction work, bedding-in condition
/ conditioning of the brake linings 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.

Mounting dimensions and connection dimensions must be
adjusted according to the size of the brake at the place of
installation.

Use of the brake in extreme environmental conditions or
outdoors, directly exposed to the weather, is not permitted.

The brakes are designed for a relative duty cycle of 50 %. A
duty cycle > 50 % leads to higher temperatures, which cause
premature aging of the noise damping and therefore lead to
an increase in switching noises. Furthermore, the switch
function of the release monitoring can be impaired. The max.
permitted switching frequency is 180 1/h.
These values are valid for intermittent periodic duty S3 50 %.
The permitted surface temperature on the brake flange must
not exceed 80 °C at a max. ambient temperature of 40 °C.
For higher requirements on the friction work in case of
EMERGENCY STOP or at temperatures of up to 90 °C on the
brake flange, special friction materials and noise damping are
to be used.

The braking torque is dependent on the current bedding-in
condition of the brake. Bedding in / conditioning of the friction
linings is necessary.

The brakes are only designed for dry running. The torque is
lost if the friction surfaces come into contact with oil, grease,
water or similar substances or any other foreign bodies.

The surfaces of the outer components have been phosphated
manufacturer-side to form a basic corrosion protection.
CAUTION
The rotors may rust up and seize up in
corrosive ambient conditions and / or after
longer downtimes.
The user is responsible for taking appropriate
countermeasures.
