Operational safety and particular hazards
Please observe the safety notes and the warnings listed here and in other chapters
of this product documentation to reduce the possibility of risks to health and avoid
dangerous situations.
The product is fitted with LEDs in risk group 0. The accessible radiation from these
LEDs does not pose a danger to the eyes or skin.
Operating the product in conjunction with external illumination systems may result in
hazardous radiation exposure. Please note the accompanying production documenta‐
tion.
CAUTION
Optical radiation: Laser class 2
The human eye is not at risk when briefly exposed to the radiation for up to 0.25
seconds. Exposure to the laser beam for longer periods of time may cause damage to
the retina. The laser radiation is harmless to human skin.
■
Do not look into the laser beam intentionally.
■
Never point the laser beam at people's eyes.
■
If it is not possible to avoid looking directly into the laser beam, e.g., during
commissioning and maintenance work, suitable eye protection must be worn.
■
Avoid laser beam reflections caused by reflective surfaces. Be particularly careful
during mounting and alignment work.
■
Do not open the housing. Opening the housing may increase the level of risk.
■
Current national regulations regarding laser protection must be observed.
Caution – Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
WARNING
Electrical voltage!
Electrical voltage can cause severe injury or death.
■
Work on electrical systems must only be performed by qualified electricians.
■
The power supply must be disconnected when attaching and detaching electrical
connections.
■
The product must only be connected to a voltage supply as set out in the require‐
ments in the operating instructions.
■
National and regional regulations must be complied with.
■
Safety requirements relating to work on electrical systems must be complied with.
WARNING
Risk of injury and damage caused by potential equalization currents!
Improper grounding can lead to dangerous equipotential bonding currents, which may
in turn lead to dangerous voltages on metallic surfaces, such as the housing. Electrical
voltage can cause severe injury or death.
■
Work on electrical systems must only be performed by qualified electricians.
■
Follow the notes in the operating instructions.
■
Install the grounding for the product and the system in accordance with national
and regional regulations.
