CAUTION
Power supply for devices with PROFINET interfaces
Modules with PROFINET interfaces may only be operated in LANs (Local Area Networks)
in which all connected devices are equipped with SELV/PELV power supplies (or have
equivalent protection).
A data transfer terminal (modem, for example) is required to access the WAN (Wide Area
Network) in order to ensure compliance with this safety standard.
All supply and signal voltages must be safety extra low voltage (SELV/PELV according to
IEC 61140).
