2 Safety
This optical data transmission system was developed, manufactured and tested in line with the applicable
safety standards. It corresponds to the state of the art.
2.1 Intended use
Devices of the DDLS 500 series have been designed and developed for the optical transmission of data
in the infrared range.
Areas of application
Devices of the DDLS 500 series are designed for the following areas of application:
• Data transmission between stationary and/or moving devices. The devices must – with respect to the
transmission beam spread - be positioned opposite one another without interruption. A data trans-
mission path consists of two identical devices which are designated with “Frequency F0” on the
name plate.
2.2 Foreseeable misuse
Any use other than that defined under “Intended use” or which goes beyond that use is considered
improper use.
In particular, use of the device is not permitted in the following cases:
• in rooms with explosive atmospheres
• for medical purposes
2.3 Competent persons
Connection, mounting, commissioning and adjustment of the device must only be carried out by competent
persons.
For information about possible restrictions regarding the transmission of special protocols see
chapter 3.1.2.

2.5 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.

The PROFINET IRT protocol is a special case. The DDLS 508 cannot satisfy the specifications
of the transmission criteria for PROFINET IRT.
For details on the delay times or the jitter-relevant device data, see chapter 4.8 "Cascading (se-
ries connection) of multiple data transmission systems".
NOTICE
Selecting transmission frequency F1 or F2!
For a given transmission path, the devices must be set to different transmission frequencies during
commissioning.
Transmission frequency F1 or F2 is configured with the operating mode selector switch [Mode] via the
FRE LED (see chapter 6.1 "Setting the operating mode").
The transmission path is correctly configured if the FRE LED on one device illuminates and does not
illuminate on the opposing device.
