2.1. Laser safety classification
The laser safety class indicates the risk potential based on the level of accessible laser radiation.
The widlaser C500 is a Class 2 (US: class II) laser system.
Integrated laser source of the widlaser C500 is a Class 4 (US: class IV) laser system.
Class 2 (US: class II)
The accessible laser radiation of Class 2 (US: class II) laser systems does not pose any hazard for the
skin. Any short-term radiation of the eyes also poses no risk due to the low-level output. In the event
of longer, more intensive radiation, the eye is protected by the natural lid reflex.
The widlaser C500 uses a Class 2 (US: class II) pilot laser. In order to prevent irritation of the eyes
during operation, the operator should not look directly at the laser source.
Diffuse reflections of the pilot laser are entirely harmless.
Class 4 (US: class IV)
High powered lasers (visible or invisible) considered to present potential acute hazard to the eye and
skin for both direct (intrabeam) and scatter (diffused) conditions. Also have potential hazard
considerations for fire (ignition) and byproduct emissions from target or process materials.
It is the responsibility of the operator of the machine to take appropriate measurements to eliminate
any dangers such as fire or explosions through the laser beam.
When dealing with class 4 (US: class IV) laser follow the following precautions:
A trained laser safety officer has to be appointed to evaluate potential hazards and to ensure that appropriate
control measures are implemented.
The laser-controlled area shall be posted with appropriate warning signs or warning lamps.
The laser-controlled area shall be defined to contain the laser radiation.
Also, it must be protected against unauthorized access.
The operator of class 4 laser systems always has to wear appropriate safety glasses.
An indicator (typically a light) to provide a warning of laser emission in advance of and during the emission
time;
2.2. Energy safety classification
The widlaser C500, requires a stable electrical connection according the following specifications, 230v AC 16A
50/60Hz.
The machine´s electrical connection must be grounded.
It is strictly forbidden to connect or operate the machine during thunderstorms and any type of electrical
instability moments or events.
In the electrical appliance manufacturing industry, the following IEC protection classes are defined in IEC 61140
and used to differentiate between the protective-earth connection requirements of devices.
