Use of the Soft Limiter function as a limiter is not permitted for
ATEX
and
IECEx
applications
according
to
IEC/IEEE 60079-30-1.
Explosion protection is not ensured by this function.
Use hardware limiter of ESTM-L (SIL II) as limiter for ATEX
and IECEx applications according to IEC/IEEE 60079-30-1.
