2. INSTALLATION
Do not connect the equipment to the mains before the installation is complete.
Do not modify the welding equipment in any way, except for the changes and adjustments covered in the man-
ufacturer’s instructions.
Place the machine on a horizontal, stable and clean ground. Protect the machine from rain and direct sunshine.
Check that there is enough space for cooling air circulation in the machine vicinity.
Before installation
• Make sure to acknowledge and follow the local and national requirements regarding installation and use of high
voltage units.
• Check the contents of the packages and make sure the parts are not damaged.
• Before you install the power source on site, see the requirements for the mains cable type and fuse rating.
Distribution network
This 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 can be potential difficulties in ensuring electromagnetic compatibility in
those locations, due to conducted as well as radiated radio-frequency disturbances.
MasterMig power source 350A: Provided that the short circuit power of public low voltage system at the point of com-
mon coupling is higher than 2.4 MVA, this equipment is compliant with IEC 61000-3-11:2017 and IEC 61000-3-
12:2011 and can be connected to public low voltage systems. 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 system impedance
complies with the impedance restrictions.
