WARNING
Unprotected cable ends
There is a risk of explosion due to unprotected cable ends in hazardous areas.
• Protect unused cable ends according to IEC/EN 60079-14.
WARNING
Improper installation of shielded cables
There is a risk of explosion due to equalizing currents between the hazardous area and the non-
hazardous area.
• Ground shielded cables that cross hazardous areas at one end only.
• Lay a potential equalization conductor when grounding at both ends.
WARNING
Insufficient isolation of intrinsically safe and non-intrinsically safe circuits
Risk of explosion in hazardous areas
• When connecting intrinsically safe and non-intrinsically safe circuits, ensure that the
galvanic isolation is performed properly in compliance with local regulations (e.g. IEC
60079-14).
• Observe the device approvals applicable for your country.
Notes for use in hazardous locations according to ATEX, IECEx, UKEX and CCC Ex
If you use the device under ATEX, IECEx, UKEX or CCC Ex conditions you must also keep to the
following safety instructions in addition to the general safety instructions for protection against
explosion:
The following information applies only to the SCALANCE X204RNA:
WARNING
Transient overvoltages
Take measures to prevent transient overvoltages of more than 40% of the rated voltage (or
more than 119 V). This is the case if you only operate devices with SELV (safety extra-low
voltage).
Safety notices when using the device according to Hazardous Locations (HazLoc)
If you use the device under HazLoc conditions you must also keep to the following safety notices
in addition to the general safety notices for protection against explosion:
