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 cables 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 electromagnetic clutch is used incorrectly.
the electromagnetic clutch is modified.
the relevant standards for safety and / or installation
conditions are ignored.
During the required risk assessment 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 professionals and
specialists are allowed to work on the devices.
They must be familiar with the dimensioning, transport,
installation, 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.
The electromagnetic clutches have been developed and
manufactured in accordance 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, released state and
secure the system against inadvertent switch-
on.
Guidelines for Electromagnetic Compatibility
(EMC)
In accordance with the EMC directive 2004/108/EC, the
individual components produce no emissions. However,
functional components e.g. mains-side energisation of the
clutches 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
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.
Mounting dimensions and connecting dimensions must be
adjusted according to the size of the clutch at the place of
installation.
The magnetic coils are designed for a relative duty cycle of
100 %.
The torque is dependent on the present run-in condition of
the clutches.
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 or foreign bodies.
The surfaces of the outer components have been zinc
phosphated manufacturer-side to form a basic corrosion
protection.
CAUTION
The rotors may rust up and block in corrosive
ambient conditions and/or after long periods of
storage.
The user is responsible for taking appropriate
counter measures.
