•
The requirements for electrical safety and electromagnetic compatibility and the regulations or standards in all
countries and/or regions, must be met by the power supply where the laser scanner is used. If the device power
supply is shared with the machine or other electronic devices, voltage fluctuations to the laser scanner or noise
influences to the scanner may occur due to temporary changes of the current consumption on the machine or the
other electronic devices. We do not recommend sharing the laser scanner power supply with the one for the machine
or the other electronic devices, because the device may go to an error state in such circumstances.
•
Do not run the connection cables in contact with or near high-voltage cables and/or cables which undergo large
current variations (i.e. motor power supplies, inverters, etc.).
•
Access to the configuration tools must be restricted to only highly qualified personnel. The configuration upload
process through the GUI is allowed only by password.

To meet the requirements of the relevant product standards (e.g. EN 61496-1), the external voltage supply for the devices (SELV) must be able to bridge a brief mains failure of 20 ms.
Power supplies according to EN 60204-1 satisfy this requirement.
3
The absolute voltage level must not drop below the specified minimum voltage.
4
The load currents for the input capacitors are not taken into account.
5
In the case of a fault (0 V cable open circuit) maximally the leakage current flows in the OSSD cable. The downstream controller must detect this status as LOW. A FPLC (fail-safe
programmable logic controller) must be able to identify this status.
6
In the case of a fault (0 V cable open circuit) maximally the leakage current flows in the OSSD cable. The downstream controller must detect this status as LOW. A FPLC (fail-safe
