Temperature Data
Temperature class Ambient temperature Ta
T4 to T1 −35 to +85 °C
T6* −35 to +50 °C*
* When using the ‘Plug-in module for digital feedback’ in temperature
class T6, the maximum permissible ambient temperature range is
−35 to +35 °C.
Special conditions
• For the ‘Feedback on the actuator position using
proximity switches (Pepperl & Fuchs SJ2
-SN )’ circuit,
measures outside of the device must be implemented to
prevent an up-scale of the rated voltage by more than
40% in the event of transient disturbances.
• Only devices that are suited for operation in hazardous
areas of Zone 2 and the conditions prevailing at the place
of use may be connected to circuits in Zone 2
(manufacturer's declaration or certificate from the test
center).
• 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 use suited cable entries that meet the requirements
of EN 60079 - 7 or EN 60079 - 15 .
