Electrical Safety
EEx ia IIC T6, Ceq=0, Leq=0; the unit can be
connected without further certification into any
intrinsically safe loop with open circuit voltage
<60V and input power <1.2W.
EEx d IIC T6; the unit is apparatus-approved to
explosionproof (flameproof) standards, and can
be fitted into a similarly approved housing.
Installation
The TP32 is designed for mounting directly into an
unused conduit entry on a fieldbus transmitter
housing (see figure 2). Generally, two such entries are
provided, one of which is used for the bus wiring. On
the unused entry, the blanking plug or other closure
device is removed and an appropriately threaded
TP32 screwed into its place. The transmitter
specification should provide information indicating the
required thread type. TP32 units can be installed
using thread adaptors (such as a tee piece) if
necessary, including certified adaptors in hazardous
area applications. For applications where two conduit
entries are not provided or where both are used for
electrical connections, TP32 units can be housed in
conventional conduit hub or junction boxes, provided
access to the loop terminals is possible.
