Special conditions
• Devices must only be connected to circuits in zone 2 if they
are suitable for operation in zone 2 potentially explosive
atmospheres and for the conditions prevailing at the
−40 to 85 °C
installation location (manufacturer's declaration or
certificate from an inspection authority).
• For the 'Limit monitor with proximity switches' circuit,
measures outside of the device must be implemented to
prevent the rated voltage from being up-scaled by more than
40 % due to transient disturbances.
• It is only permissible to connect, disconnect, and switch live
circuits during installation or maintenance, or for the
purpose of carrying out repairs. Note: It is considered very
unlikely that a potentially hazardous atmosphere would be
present in zone 2 at the same time that installation or
maintenance or repair work was being carried out.
