SPECIFIC DANGERS

Electrical Energy

In the F-Series laser marking system, the maximum operating voltage is the
connected mains voltage, which can pose a hazard to health. The mains
voltage to be maintained is shown on the name plate.
Work on live components must only be performed by authorised personnel.
In the case of a defective power supply, operation of the laser marking
system is to be stopped immediately and is only to be repaired by
authorised personnel.
Keep the control unit closed at all times. Only expressly authorised
personnel are permitted to open the control unit.

Laser Radiation

Laser radiation can pose a risk to eyes and skin. The danger is not only
posed by direct laser radiation, but also by scattered radiation and
reflections from the work piece or the packaging machine. The degree of
injury depends on the duration of the effect, the power and the wavelength
of the laser.
Lasers and their installations are classified into seven laser protection
classes, depending on their potential danger. Class 1 is the safest and
Class 4 is potentially the most harmful. These classes are defined in detail
in EN60825 Part 1 and are summarised below:
Class 1 The accessible laser radiation may be visible or invisible and is
harmless.
Class 1M The accessible laser radiation may be visible or invisible and is
harmless, provided additional optical instruments are not used.
Class 2 The accessible laser radiation is visible and is harmless for
accidental exposure to eyes for periods of less than 0.25
seconds.
Class 2M The accessible laser radiation is visible and is harmless for
accidental exposure to eyes for periods of less than 0.25
seconds, provided additional optical instruments are not used.
Class 3R The accessible laser radiation may be visible or invisible. It is
potentially harmful to eyes.
Class 3B The accessible laser radiation may be visible or invisible. Direct
radiation is harmful to the eyes and skin although diffuse
radiation (reflected from a matt surface) is harmless.
