11.1.3- Following these procedures is essential to realize an installation which complies with the
requirements of 2014/30/CE directive. The real specific standard compliance have to be proved in
the complete installation. In fact the effectiveness of the suggested application notes depends also
on machine topology and on the measurement setup. Test performed by R.T.A. simulating typical
installations and following the mentioned above indications show that EN61800-3 standard
compliance applications can be achieved.
11.1.4- In some cases, due to the characteristics of particular installations, conflicts between ground
connections necessary for shielding purposes and ground connections necessary for safety reasons
could arise. Remember that, in such cases, prescriptions regarding safety take priority, but
remember also that, in almost all of the cases it is possible to find a solution meeting both
prescriptions; R.T.A. is available for further information about these problems.
