Special Conditions for Safe Use(X):
1. This 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 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. 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.
4. Appropriate cable, glands and plugs need to be suitable
for a temperature of 5 °C greater than maximum specified
temperature for location where installed.
