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.
Clutches 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 clutch brake unit is used incorrectly.
the clutch brake unit 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 clutch 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 clutch brake units
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-energised, disengaged state
and secure the system against inadvertent
switch-on.
Guidelines for Electromagnetic Compatibility
(EMC)
In accordance with the EMC directives 2014/30/EU, the
individual components produce no emissions. However,
functional components e.g. mains-side energisation of the clutch
brake units with rectifiers, phase demodulators, ROBA
®
-switch
devices, ROBA
®
-takt control units, ROBA
®
-takt circuit modules 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
clutch brake units, 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 clutch brake unit at the
place of installation.
The clutch brake units are designed for a relative duty cycle
of 100%.
The braking torque is dependent on the current bedding-in
condition of the brake. Bedding in / conditioning of the
friction linings is necessary.
The clutch brake units 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.
CAUTION
The friction surfaces may rust up and seize up
in corrosive ambient conditions and / or after
longer downtimes.
The user is responsible for taking appropriate
countermeasures.
