Special Conditions for Safe Use (X):
1. The enclosure may be made from aluminium alloy with a protective polyurethane paint
finish which may constitute a potential electrostatic ignition risk. Care should be taken
to protect it from external conditions conducive to the build-up of electrostatic charge
on such surfaces. The enclosure must not be rubbed or cleaned with a dry cloth.
2. When the equipment is installed, particular precautions must be taken to ensure,
taking into account the effect of process fluid temperature, that the ambient
temperature of the electrical housing of the equipment meets the marked protection
type temperature range.

Installation instructions:
1. The cable and conduit entry devices shall be of a certified flameproof type Ex d, suitable
for the conditions of use and correctly installed.
2. Unused apertures shall be closed with suitable blanking elements.
3. When the ambient temperature at the cable or conduit entries exceed 60 °C, cables
suitable for at least 90 °C shall be used.
4. The remote mounted sensor may only be connected to the transmitter with the
associated cable, supplied by the manufacturer.
Special Conditions for Safe Use (X):
1. For information regarding the dimensions of the flameproof joints, the manufacturer
shall be contacted.
2. The Flowmeter shall be provided with special fasteners of property class A2-70 or
A4-70.
3. Units marked with "Warning: Electrostatic Charging Hazard" may use non-conductive
paint thicker that 0.2 mm. Precaution shall be taken to avoid ignition due to
electrostatic charge on the enclosure.
