• Please observe the accident prevention regulations of the country in question.
• Ensure good lighting of the work area and keep the work area clean.
Observe in particular the following standards and directives:
• 89/391/EEC: Implementation of measures for improving safety and health requirements for workers at
work.
• 89/655/EEC: Minimum safety and health requirements for the use of work equipment by workers at
work.
• DIN EN 60974-4: Equipment for arc welding part 4: Periodic inspection and checking
• DIN EN 60974-9: Equipment for arc welding part 9: Set up and operation.
• Occupational health and safety regulations of the country in question. For example, Germany:
Occupational Health and Safety Act and Ordinance on Industrial Safety and Health

• According to DIN EN 60974-10, this device is considered class A welding equipment. The class A
welding equipment is not intended for use in residential areas with a public low-voltage power supply
system. Such use can cause electromagnetic interferences that may result in machine damage and
malfunctions. Use the device only in industrial areas.
• The device conforms to EN/IEC 61000-3-11.
• This device complies with the standard DIN EN 61000-3-12, provided the maximum allowed system
impedance ZMAX at the interface between the supply line of the user and the public system is smaller
or equal to 0.038 ohms for iROB P 500, 0.06 ohms for iROB P 400. It is the installer's or operator's
responsibility to ensure, if necessary by consultation with the distribution network provider, that the
device is only connected to a connection that has a maximum allowed system impedance of less than or
equal to 0.038 ohms for iROB P500, 0.06 ohms for iROB P 400.
