Special Conditions for Safe Use (X):
1. This device contains a thin wall diaphragm less than 1 mm thickness
that forms a boundary between Class 1, Zone 0 (process connection)
and Class 1, Zone 1 (all other parts of the equipment). The model code
and datasheet are to be consulted for details of the diaphragm
material. Installation, maintenance and use shall take into account the
environmental conditions to which the diaphragm will be subjected.
The manufacturer's instructions for installation and maintenance shall
be followed in detail to assure safety during its expected lifetime.
2. Flameproof joints are not intended for repair.
3. Appropriate cable, glands, and plugs need to be suitable for a
temperature of 5 °C greater than the maximum specified temperature
for location where installed.
4. The applicable temperature class, ambient temperature range and
process temperature range of the equipment is T4 for –50 ≤ T
a
≤ 80 °C
with T process = –50 to 120 °C.
5. Non-standard paint options (paint options other than Rosemount
Blue) may cause risk from electrostatic discharge. Avoid installation
that could cause electrostatic build-up on painted surfaces, and only
clean the painted surfaces with a damp cloth.
6. Display glass shall be positioned in such a way as to minimize the risk
of mechanical impact.
