Electromagnetic compatibility
Electromagnetic compatibility (EMC) mainly concerns the emission of electromagnetic
interference and the immunity of electronic components and systems to this interference.
If the following interference suppression measures are correctly installed and applied, the
equipment will not cause any electromagnetic interference above the level permissible for
the intended operating environment and have sufficient resistance to electromagnetic
interference to function without error.
Detailed information on EMC-compliant installation is given in a separate instruction
manual. The system builder is responsible for the EMC of the system as a whole.
In general, the product is designed
for the operating environment “industrial environment”,
or “2nd environment”
in the case of use of frequency-controlled drives.
The electronic control devices of the overload protection and any frequency inverters
installed are interference-suppressed. You will find further information in the relevant
operating instructions of the devices.
The contacts of power contactors and rectifiers for motor brakes may generate
interference exceeding the permissible values depending on output, cable length and
other system parameters.
Ready-to-connect electric wire rope hoists with declaration of conformity complying with
machinery and EMC directives are interference-suppressed for the above operating
environment.
No particular protective measures have been taken on electric wire rope hoists with
control by customer or crane builder's control. Appropriate precautions must be taken by
the customer in order to comply with EMC standards with regard to interference values.
In order to achieve an optimum result with minimum outlay, we recommend using our
radio interference suppression module FEM1 for the YK/SK wire rope hoist.
