2 Safety notes
The following basic safety notes must be read carefully to prevent injury to persons
and damage to property. The user must ensure that the basic safety notes are read
and observed. Make sure that persons responsible for the system and its operation,
as well as persons who work independently on the unit, have read through the operat-
ing instructions carefully and understood them. If you are unclear about any of the in-
formation in this documentation, or if you require further information, please contact
SEW-EURODRIVE.
2.1 Preliminary information
INFORMATION
Due to the strong permanent magnets installed in the secondaries of the SLC linear
motors, the following safety regulations must be observed.
Also observe the additional safety notes provided in the individual chapters of this
documentation.
Due to the strong magnetic fields persons with cardiac pacemakers must not perform
work on these units.
Even at a distance of 100mm, the magnetic flux density of the present secondaries is
< 2 mT (at 150mm < 1 mT). Since the magnetic flux density in SLC linear motors is
generated exclusively by the magnetic fields of the secondaries, this value is inde-
pendent from the operating status of the SLC linear motor.
Be cautious when in close proximity (distances < 50mm) to the secondaries due to
the high attraction forces. Magnetic forces are often underestimated since they are not
visible.
Magnetic attraction forces often start abruptly in the immediate proximity range and
can grow in up to 100kg for medium-sized objects.
