■ Use only appropriate intrinsically safe equipment with a
separate EC-type examination certificate, with which the
permissible electrical limit values of the intrinsically safe
circuit will not be exceeded.

The maximum effective capacitance and inductance are
negligibly small.
WARNING!
The ambient temperature of the current-loop display can
be altered by additional components (e.g. through heat
dissipation in the case, in particular with a transmitter
mounted within the case or by mounting it in the connection
head of a temperature sensor with the radiated heat from
the process medium). The operator of the display must
ensure that, even in the event of a failure, the maximum
permitted ambient temperature of 60 °C is not exceeded.
The programming set for the factory programming must
only be used by the manufacturer, as it does not have
ATEX approval!
The programming of the display must only be made via the
three buttons at the rear of the display!
