9. Information on mounting and operation in hazardous areas
In hazardous areas, only use field instruments that are approved for those hazardous
areas. The approval is marked on the product label.
When connecting them to other devices or component, observe the connection
requirements regarding explosion protection, such as maximum admissible voltage, power
or load with capacitances (see chapter 9.1 "Model overview and their approvals" and
9.2 "Special conditions for safe use models TIF50-F, TIF52-F").

9.2 Specific conditions for safe use models TIF50-F, TIF52-F
Cables, insertions and blind plugs must be suitable for the corresponding Ex classification
as well as for the corresponding operating temperature. Observe the operating instructions
and approvals of the threads and conduit systems used. You must therefore check in the
final application case (e.g. ambient temperature plus 5 K) whether the components used
are suitable. The instruments may not be opened while they are under voltage.
Observe the warnings on the instruments:
"WARNING! – do not open while under voltage"
