in the connection box. The rotational direction of one
phase motors has been set correctly by the manufacturer.
Once connected, ensure that the junction box and the
threaded cable connection are screwed down correctly.
The dust extractor has to be connected to the machine
in such a way as to be operating automatically when
the bandsaw is switched on. An induction switch in the
machine feed line will execute this function.
Specifications
The electrical connection may only be carried out by a
competent and qualified person with the appropriate
training. The main connection is in the terminal box.
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 current 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
4.4 Noise emission
The specified values are emission values and therefore
do not represent safe workplace values. Even though a
relationship exists between particle emission and noise
emission levels, an inference cannot be made about
whether additional safety measures need to be imple-
mented. Factors which can significantly affect the emis-
sion level that presently exists at the workplace include
duration of the effect, characteristics of the workspace,
and other ambient influences.
The permissible workplace values may also differ from
country to country. Nevertheless, this information is
provided to help the operator better assess 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.
To keep the noise emission as low as possible, always
used sharpened tools and use the correct speed.
It is recommended to use protective ear equipment, this is
however not a substitute for properly sharpened tools or
the correct operating speed.
Attention! The neutal conductor has to be connected so that the brake can be bled (released). If a neutral
conductor is not present, the customer has to install one.
