1.7.1 EMC classification in accordance with: EN 60974-10/A1:2015.
Class B equipment complies with electromagnetic compatibility requirements in industrial and residential
Class B
environments, including residential locations where the electrical power is provided by the public low-voltage
supply system.
Class A equipment is not intended for use in residential locations where the electrical power is provided by the public
low-voltage supply system. There may be potential difficulties in ensuring electromagnetic compatibility of class A
Class A
equipment in those locations, due to conducted as well as radiated disturbances.
For more informations, check the chapter: RATING PLATE or TECHNICAL SPECIFICATIONS.
1.7.2 Installation, use and area examination
This equipment is manufactured in compliance with the requirements of the harmonized standard EN 60974-10/A1:2015 and is
identified as "CLASS A" equipment. This unit must be used for professional applications only, in industrial environments. The
manufacturer will accept no responsability for any damages caused by use in domestic environments.
The user must be an expert in the activity and as such is responsible for installation and use of the equipment
according to the manufacturer's instructions. lf any electromagnetic interference is noticed, the user must solve the
problem, if necessary with the manufacturer's technical assistance.
In any case electromagnetic interference problems must be reduced until they are not a nuisance any longer.
Before installing this equipment, the user must evaluate what electromagnetic problems it might cause in the
surrounding area, with specific regard to the health of persons nearby, pace-maker and hearing aid users, for
example.
1.7.3 Mains power supply requirements
The high current draw of high-power equipment can affect the quality of mains electrical energy. Connection restrictions or
requirements regarding maximum permissible mains impedance (Zmax) or minimum supply capacity (Ssc) at the point of
interface with the public grid (point of common coupling, PCC) may apply for certain types of equipment (see technical data). In
this case it is the responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network
operator if necessary, that the equipment may be connected. In case of interference, it may be necessary to take further
precautions like the filtering of the mains power supply.
lt is also necessary to consider the possibility of shielding the power supply cable.
For more informations, check the chapter: TECHNICAL SPECIFICATIONS.
1.7.4 Precautions regarding cables
To minimise the effects of electromagnetic fields follow the following instructions:
• Where possible, collect and secure the earth and power cables together.
• Never coil the cables around your body.
• Do not place your body in between the earth and power cables (keep both on the same side).
• The cables must be kept as short as possible, positioned as close as possible to each other and laid at or approximately at
ground level.
• Position the equipment at some distance from the welding area.
• The cables must be kept away from any other cables.
1.7.5 Earthing connection
consideration. The earthing connection must be made according to the local regulations.
1.7.6 Earthing the workpiece
When the workpiece is not earthed for electrical safety reasons or due to its size and position, the earthing of the workpiece may
reduce the emissions. It is important to remember that the earthing of the workpiece should neither increase the risk of accidents
for the user nor damage other electric equipment. The earthing must be made according to the local regulations.
1.7.7 Shielding
The selective shielding of other cables and equipment present in the surrounding area may reduce the problems due to
electromagnetic interference.
The shielding of the entire welding equipment can be taken in considered for special applications.
