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.
5. The user must ensure that the maximum rated voltage and current (36
volts, 24 milliamps, d.c.) are not exceeded. All connections to other
apparatus or associated apparatus shall have control over this voltage
and current equivalent to a category 'ib' circuit according to EN 50020.
6. Cable entries must be used which maintain the ingress protection of
the enclosure to at least IP66.
7. Unused cable entries must be filled with suitable blanking plugs which
maintain the ingress protection of the enclosure to at least IP66.
8. Cable entries and blanking plugs must be suitable for the ambient
range of the apparatus and capable of withstanding a 7J impact test.
