Special Conditions for Safe Use (X):
1. This device contains a thin wall diaphragm less than 1 mm thick that
forms a boundary between EPL Ga (process connection) and EPL Gb
(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 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. Some variants of the equipment have reduced markings on the
nameplate. Refer to the Certificate for full equipment marking.
