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.
• 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
-

.
In the case of TZIDC, the following shall apply for safe use in
the Ex ‘ec IIC’ type of protection:
• 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).
