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 5.6 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 5.6 MVA.
NOTE! The above applies only when connected to the mains supply of 380...440 V 3~.
