4.1Safety notice

Only use the PROFIBUS OLM as described in this ”Description and Operating Instructions“. Pay particular attention to all the warnings and safety instructions.

Only operate the modules with a safety extra-low voltage in accordance with IEC 950/EN 60 950/VDE 0805 with a maximum rating of +32 V (typically +24 V).

The power source must comply with NEC, Class 2, regulations as stipulated by UL/CSA.

Pay attention to the electrical limit values when connecting the power supply to the signaling contacts: max. voltage 60 V DC, 42 V AC.

The connected power supply must also be safety extra-low voltage in accordance with IEC 950/ EN 60 950/ VDE 0805 and comply with NEC, Class 2, regulations as stipulated by UL/CSA.
