In case of protection by means of automatic circuit breakers, it is recommended to use C-curve devices con-
form to IEC 60947-2 standard. The following table shows the recommended solutions:
5.5.3 EMI filtering
The power supply is designed to operate according to IEC 61800-3 standards (second environment, category
C3). However, the emission levels strictly depends on the emissions generated by downstream devices. Since
the servodrives are not equipped with EMI filter, it will be necessary to install an external EMI filter in order to
comply with the emission levels required by the standards actually in force.
The selection process of the filter must take into consideration the following data:
• mains voltage;
• max input current;
• required insertion loss.
Unfortunately, it is not possible to size the filter in advance, because it depends on several factors, such as the
number and type of downstream devices, the rules in force, the absorbed currents, etc...; therefore, it will have
to be validated on the field, measuring the emission level.
