Electromagnetic compatibility

To evaluate overall operator safety, we must also consider machine behaviour, with reference to both the main frequencies that interact with the human body, and the degree of immunity of the machine to the electromagnetic fields produced by the environment where it’s used. Let’s analyse each aspect separately.

Electromagnetic field emissions of the machine at frequencies which interact with the human body. EN 62233Exposure to the electromagnetic fields of daily-use devices (mobile phones, high voltage cables etc.) is presently the subject of several studies in the medical field.
These studies seem to underline a correlation between exposure to certain electromagnetic fields and the onset of some types of tumour.
That’s why it’s important to ensure that all the equipment we use guarantees the lowest levels of electromagnetic field emissions.
With regard to machines, the European standard EN 62233 defines the test methods.
The declaration of conformity, which comes with the machine, must state the conformity of the machine with this standard. The machine with the lowest level of emissions is recommended.

Make sure the machine complies with standard EN 62233. Whenever possible, choose the machine which ensures the lowest level of emission!

The conformity of our machines with standard EN 62233 is certified by an accredited laboratory, to guarantee maximum operator safety.

Machine immunity to environmental EM fields. EN 61000-6 – EN 55014As the machines also contain electronic devices, you must evaluate their sensitivity to the electromagnetic fields in the places where the machine will be used.
In this respect, two types of environment are identified: the residential environment consisting of all those places where there is a maximum voltage of 220 V; the industrial environment </b> consisting of all those places where there is an alternate mains voltage above 220 V.
Given the definition, the residential environment includes houses, supermarkets, hospitals and so on; the industrial environment includes, for instance, companies utilising three-phase powered equipment.
Environmental electromagnetic fields interfering with the machine electronics may cause the malfunctioning of the machine itself, with consequential risks for the operator’s safety.
It’s therefore important to read the declaration of conformity of the machine, to check its immunity level is suitable for the environment where it will be used; to do this, just check the standard used as a reference to measure machine immunity.

Make sure the machine complies with the standard stating the most suitable level of immunity for the environment where it will be used.
The reference standards are:
EN 61000-6-1 for residential environments
EN 61000-6-2 for industrial environments
EN 55014-2 for cable-powered machines.

The immunity of our machines to EM fields in residential environments is certified by an accredited laboratory, to guarantee maximum operator safety.

Machine emissions in the surrounding environment.To assess whether a machine is suitable for use in a given environment, the electromagnetic wave emissions of the machine must be measured and compared with the intrinsic requirements of the environment it operates in.
In residential environments, where there is a maximum mains voltage of 220V, the lowest possible levels of emissions (and however below the limits set by the EN 61000-6-3 directive), must be assured.
In industrial environments, on the other hand, since machines that “generate” electromagnetic pollution in the environment are normally used, there are less strict limitations, as established by EN 61000-6-4 standard.
Given the definition, the residential environment includes houses, supermarkets, hospitals and so on; the industrial environment includes, for instance, companies utilising three-phase powered equipment.
The electromagnetic fields produced by the machine may cause anomalies in nearby equipment, involving some risk for people who depend on such equipment.
It’s therefore necessary to check the declaration of conformity of the machine, to ensure the emission level is compatible with the environment where it will be used; to do this, just check the standard used as a reference to measure machine emissions.

Make sure the machine complies with the standards for the emission levels required in the workplace.
The reference standards are:
EN 61000-6-3 for residential environments
EN 61000-6-4 for industrial environments
EN 55014-1 for cable-powered machines.

The levels of EM field emissions of our machines comply with the requirements for residential environments. Their compliance is certified by an accredited laboratory to offer the highest reliability.
