7 Installation and Startup

7.1Notes on Safety

âUse the PROFIBUS ILM only as described in this “description and operating instructions”.

âNever connect the PROFIBUS ILM to the mains power supply 110 V – 240 V.

âIn particular, take note of all the warnings and notes relating to safety.

âThe operating voltage must be a safety extra-low voltage complying with IEC 950/EN 60 950/VDE 0805 of maximum +30V (typically )24 V). According the CUL approval you should connect the PROFIBUS ILM only at the load side of a Class 2 or Class 3 Power source as defined by the National Electric Code (NEC), Article 725–2 and the Canadian Electrical Code (CEC).

âThe voltage connected to the signalling contact must be a safe extra-low voltage complying with IEC 950/EN 60 950/ VDE 0805 According the CUL approval you should connect the signalling contact only at the load side of a Class 2 or Class 3 power source as defined by the National Electric Code (NEC), Article 725–2 and the Canadian Electrical Code (CEC).

âWiring the PROFIBUS ILM, pay attention to the wiring methods described in NEC article 725–52, 725–54, 725–61 and 725–71.

âSelect a site to install the module so that the climatic limit values listed in the technical specifications are not exceeded.
