Motors with Exn, Group II, T3 certification

[sykimk]

I am not familiar with hazardous area classification defined by IEC/CENELEC.
Please advise whether it is acceptable to use motors with "Exn, Group II, T3" certification in the area of Zone 2, group IIC, T3.
As far as I know, "Exn" motors are non-sparking design. Therefore, I think it is acceptable to use those motors in the Zone 2 area regardless of gas group.
Please advise anything else that I missed.

Thanks in advance for your kindness and any tips.
