1 Safety
1.1
Explanation of symbols
This symbol is used for all points in these operating instructions to which special
attention is to be paid so that all directives, regulations, instructions and the correct
work sequence are observed, and to prevent minor or serious damage to the laser
system or plant.
1.1.1 General safety instructions
The operating instructions and the safety instructions are to be read and observed
prior to installation and commissioning!
The operating instructions must be read,
understood and followed by the operators responsible for the unit. Along with the
in structions in these operating instructions, also observe the generally applicable
safety and accident prevention regulations!
All work on installation and commissioning
as well as all maintenance is to be performed by appropriately qualified personnel.
National accident prevention regulations, EN and IEC standards are to be observed.
Appropriately qualified personnel in the context of these basic safety instructions are
persons who are familiar with the fitting, installation, placing in operation and operation
of the product and have qualifications appropriate to their task.
1.1.2 Laser safety
The unit is a class 3B laser device. Both the direct beam and its reflections from
di ffuse reflective surfaces are dangerous.The unit emits strong power beams in the
visible spectral range (approx. 400 nm to 700 nm, for more detailed information see
the data sheet, page 14). The radiation can cause irreversible damage to the eyes if the
necessary protective measures are not taken.
1.1.3 Laser area
The laser area is the area in which the values for the maximum permissible irradiation
can be exceeded. Here the possibility of unintentional deflection of the laser beam is
also to be taken into account. If operational equipment other than that given in this
manual or another procedure is used, dangerous exposure to the radiation may result.
Laser system screened inside a protective cover
By using suitable screening it can be ensured that people are not exposed to the laser
radiation. In this way the laser class is reduced and it is possible to work with the
closed arrangement without additional limitations or further measures.
