Special Conditions for Safe Use (X):
1. The device contains a thin wall diaphragm less than 1 mm thickness
that forms a boundary between zone 0 (process connection) and 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 shall be subjected. The
manufacturer's instructions for installation and maintenance shall be
followed in detail to assure safety during its expected lifetime.
2. Appropriate cable, glands and plugs need to be suitable for a
temperature of 5°C greater than maximum specified temperature for
location where installed.
3. Flameproof joints are not intended for repair.
4. Non-standard paint options may cause risk from electrostatic
discharge. Avoid installations that could cause electrostatic build-up
on painted surfaces, and only clean the painted surfaces with a damp
cloth. If paint is ordered through a special option code, contact the
manufacturer for more information.
