Explosion hazard from contact with potentially explosive atmosphere
When working in hazardous areas, there is an explosion hazard from sparking.
The sparks can ignite the surrounding explosive atmosphere.

intrinsically safe circuits are protected by a cover with a degree of protection IP30
according to IEC/EN 60529.
• Only remove the plug-in module in the hazardous area, if the non-intrinsically safe circuits
are protected by a cover with a degree of protection IP30 according to IEC/EN 60529.
Danger!
Explosion hazard from missing cover
If non-intrinsically safe circuits come into contact with electrically conductive objects, a spark
can occur that can ignite an explosive mixture.
• Protect the non-intrinsically safe circuits with a cover that is rated with the degree
of protection IP30 according to IEC/EN 60529.
• Use the supplied parts to ensure the required degree of protection.
• Place warning marking "Warning – Non-intrinsically safe circuits protected by internal
cover with a degree of protection IP30!" visibly next to base module.
The national requirements apply to maintenance, servicing, and inspection
of associated apparatus.
