2.1 positioning of the machine
Place the machine on a firm, dry and level surface. Where possible, do not allow dust or other
impurities to enter the machines cooling air flow. Preferably site the machine above floor level;
for example on a suitable carriage unit.
Notes for positioning the machine
• The surface inclination should not exceed 15 degrees.
• Ensure the free circulation of the cooling air. There must be at least 20 cm of free space in
front of and behind the machine for cooling air to circulate.
• Protect the machine against heavy rain and direct sunshine.
Note! the machine should not be operated in the rain as the protection class of the machine, IP23S,
allows for outside preserving and storage only.
NOTE! Never aim metallic grinding spray/sparks towards the equipment.
2.2 Distribution network
All regular electrical devices without special circuits generate harmonic currents into
distribution network. High rates of harmonic current may cause losses and disturbance to some
equipment.
This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is
greater than or equal to 4.7 MVA at the interface point between the user’s supply and the
public supply network. 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 is
connected only to a supply with a short-circuit power Ssc greater than or equal to 4.7 MVA.
2.3 Connection to the mains supply
FastMig power sources are delivered equipped with 5 m mains cable without plug.
If local electricity regulations of operating country are stating otherwise, the mains cable should
be replaced in conformity with the local regulations.
Connection of the mains cable, mounting and change of the plug should only be carried out by
a competent electrician.
Remove the machine’s right side plate to enable the mounting of a mains cable.
KMS 400 MVU power source can be connected to the mains supply of 230 V 3~ or 400 V 3~ .
if changing the mains cable take into consideration the following:
The cable is entered into the machine through the inlet ring on the rear panel of the machine
and fastened with a cable clamp (05). The phase conductors of the cable are coupled to
connectors L1, L2 and L3. The earth protection coloured green-yellow is coupled to connector.
Note! If you are using 5-lead cable, do not connect neutral conductor.
