• The device (terminal head) must be connected to the potential
equalization line.
• The certified display, type TID10, may only be installed in Zone 1/EPL
Gb or Zone 2/EPL Gc.
• The permitted ambient temperatures for display type TID10 must be
observed.
During installation, ensure that the distance between the intrinsically
safe circuits and the non-intrinsically safe circuits is a tight string
length of 50mm.
• The housing of the field transmitter must be connected to the
potential matching line.
• The circuits of the installed head transmitter are insulated from its
housing in accordance with EN/IEC 60079-11 Section 6.3.13.
(These specifications must be observed only if the device is installed
directly in Zone 0 (Category 1)/EPL Ga.)
• Explosive steam/air mixtures may only occur under atmospheric
conditions.
• –50 °C ≤ Ta ≤ +60 °C
• 0.8 bar ≤ p ≤ 1.1 bar
• If no explosive mixtures are present, or if additional measures have
been taken in accordance with EN 1127-1, the instruments may also
be operated outside the atmospheric conditions in accordance with
the manufacturer' s specifications.
• The ambient temperature restrictions outlined in EN 1127-1 6.4.2
must be observed (see table).
• The circuit to be supplied must comply with Ex ia IIC type of
protection (EN/IEC 60079-14 12.3).
• The measuring devices may be used only in media to which the
process-wetted materials have a sufficient level of resistance.
• When operating the complete device in Zone 0/EPL Ga, the
compatibility of the device materials with the media must be
guaranteed. (Housing: polycarbonate (PC), cast: silicone).
• The installation of display TID10 in Zone 0/EPL Ga is not permitted.
• The temperature transmitter must be mounted in such a way that
electrostatic charging cannot occur, for example by installing in a
grounded metallic head or grounded housing.
