Only for connection to a programming device

the hazardous area.
Special conditions
In the case of TZIDC-110, TZIDC-120, 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).
• For the ‘Mechanical digital feedback with Pepperl & Fuchs
SJ2-SN proximity switches’ circuit, external measures
must be implemented outside of the device to prevent
the rated voltage from being up-scaled 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 cable entries may be used that suit the requirements
of EN 60079-7 or EN 60079-15.
