Special Conditions for Safe Use (X):
1. This device contains a thin wall diaphragm with 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.
