Prerequisites for competent persons:
• They have a suitable technical education.
• They are familiar with the rules and regulations for occupational safety and safety at work.
• They are familiar with the original operating instructions of the device.
• They have been instructed by the responsible person on the mounting and operation of the device.
Certified electricians
Electrical work must be carried out by a certified electrician.
Due to their technical training, knowledge and experience as well as their familiarity with relevant stan
-
dards and regulations, certified electricians are able to perform work on electrical systems and indepen
-
dently detect possible dangers.
In Germany, certified electricians must fulfill the requirements of accident-prevention regulations BGV A3
(e.g. electrician foreman). In other countries, there are respective regulations that must be observed.
2.4

Leuze electronic GmbH + Co. KG is not liable in the following cases:
• The device is not being used properly.
• Reasonably foreseeable misuse is not taken into account.
• Mounting and electrical connection are not properly performed.
• Changes (e.g., constructional) are made to the device.

Laser safety notices
Laser diode of the transmitter – laser class 1M
The device emits invisible laser radiation at a wavelength of 785 nm through the laser aperture of the
optical window. The opening angle of the beam cone is ≤ 1° (± 0.5°).
The power density distribution in the light spot is homogeneous; there is no elevation of power density in
the center of the light spot. The average emitted laser power of the device is < 12 mW. For transmission
of the data, the emitted laser radiation is amplitude modulated (on-off keying). Pulses and pulse pauses
of the emitted laser light are between 8 ns and 32 ns long. The laser power emitted during the pulses is
< 24 mW.
ATTENTION, INVISIBLE LASER RADIATION – LASER CLASS 1M
Never observe directly using telescope optics!
The device fulfills the IEC 60825-1:2007 (EN 60825-1:2007) requirements for a product in laser class 1M
as well as the U.S. 21 CFR 1040.10 regulations with deviations corresponding to “Laser Notice No. 50”
from June 24th, 2007.
Looking into the beam path for extended periods using telescope optics may damage the eye's retina.
Never look using telescope optics into the laser beam or in the direction of reflecting beams.
CAUTION! The use of operating or adjusting devices other than those specified here or carrying out
of differing procedures may lead to dangerous exposure to radiation.
The use of optical instruments or devices (e.g., magnifying glasses, binoculars) with the product will
increase eye danger.
Observe the applicable statutory and local laser protection regulations.
The device must not be tampered with and must not be changed in any way.
There are no user-serviceable parts inside the device.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.
