Technical data
The electrical connection may only be carried out by a
competent and qualified person with the appropriate
training.
Ensure that the mains supply is correct for the machine
and use connecting cables with a cross-section appropri-
ate to the power consumption of the drive motor.
The minimum conductor cable size is 2,5 mm for a 400V
supply. If the mains voltage is 230V or has a rated cur-
rent above 15 A, it is necessary to use higher capacity
cabling.
Connect the 3 phases with the R-S-T clamps (L1-L2-L3)
and the yellow-green electrical conductor with the earth-
ing clamp (Pe).
When the machine is first switched on, check the rota-
tional direction and if incorrect, exchange two phases in
The given values are emission values and not safe work-
place values. Although there is a correlation between
emission and immission levels, it is not possible to state
whether increased safety measures are required.
Factors which can considerably influence the present
immission level at the workplace include the duration of
exposure, the character of the work area and other influ-
ences in the neighbouring area.
Acceptable workplace values may also vary from country
to country. However, this information should help the user
to better assess the hazards and risks.
Depending on the installation location and other vari-
ables, the resulting noise emission can differ by up to 4
db (A) from the given values.

17
The following points are important for a correct and ef-
ficient machine installation:
• The machine should be bolted to the floor with M10
screws for optimum stability, however take care not
to overtighten the fastening bolts as this will increase
vibrations. It is advisable to place vibration dampen-
ing pads between the floor and the machine.
• Install the machine in such a way as not to amplify
the vibrations and machine noise.
• Ensure that workplace lighting is adequate.
• If the machine is to be installed between other ma-
chines, leave at least 80 cm distance in order to
avoid collisions when cutting large work-pieces and
to allow the use of equipment such as roll supports
and additional tables.
