Special Conditions for Safe Use (X):
1. The 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. Installation, maintenance, and
use shall take into account the environmental conditions to
which the diaphragm will be subjected. The manufacturer's
instructions for 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
