Temperature Data
Temperature class Ambient temperature Ta
T4 − 40 to 85 °C
T6* − 40 to 40 °C*
* When using the ‘Limit Monitor’ plug-in module in temperature class T6, the
maximum permissible ambient temperature range is − 40 to 35 °C
( − 40 to 95 °F).

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
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.
• Only non-flammable gases must be used for pneumatic
power supply.
• Only suited cable entries must be used that meet the
requirements of EN 60079-15.
• The local communication interface (LCI) for the TZIDC and
the TZIDC-200 may only be operated at U
m
≤ 30 V GS outside
the hazardous area.
