5.3 Operating limits
PROHIBITION! This product is not designed or
intended for use in hazardous environments
(due to the presence of potentially explosive
atmospheres - ATEX or with required IP level
higher than that of the unit) or in applications
requiring safety features (fault-tolerant, fail-safe)
which may be systems and/or technologies to
support life or any other context in which the
malfunction of an application can lead to death
or injury to people or animals, or serious dam-
age to property or the environment.
NB!: If the possibility of a product fault or failure can
cause damage (to people, animals and property) it is nec-
essary to provide for a separate functional surveillance
