If the cable or conduit entry point exceeds 70°C or the branching point of conductors
exceeds 80°C, special precautions must be taken. If the equipment is operated in an air
ambient in excess of 50 °C to 70 °C, only use cables with admitted maximum operating
temperature of at least 80 °C.
WARNING
Protection against transient voltage surges
Take measures to prevent transient voltage surges of more than 40% of the rated voltage.
This is the case if you only operate devices with SELV (safety extra-low voltage).
Safety requirements 100 to 240 VAC (SCALANCE X204RNA EEC only)
Safety requirements for installation
According to the IEC 61131-2 standard and therefore in accordance with the EU directive
2006/95/EC (Low Voltage Directive), the devices are "open equipment" and in accordance
