Special Conditions for Safe Use (X):
1. This device contains a thin wall diaphragm less than
1 mm thick that forms a boundary between Category
1G (process connection) and Category 2G (all other parts
of the equipment). The model code and datasheet are
to be consulted for details of the diaphragm material.
During installation, maintenance, and use, the environmental
conditions to which the diaphragm will be subjected shall
be taken into account. 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 to be repaired.
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. Some variants of the equipment have reduced markings on
the nameplate. Refer to the Certificate for full equipment
marking.
5. Variants with a paint finish must not be installed in a dust-
laden airflow.
