Special Conditions for Safe Use (X):
1. The device contains a thin wall diaphragm. 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. The Ex d blanking elements, cable glands, and wiring shall be suitable for a temperature
of 90 °C.
3. In case of repair, contact the manufacturer for information on the dimensions of the
flameproof joints.

Special Conditions for Safe Use (X):
1. If the equipment is fitted with an optional 90 V transient suppressor, it is incapable of
withstanding the 500 V isolation from earth test and this must be taken into account
during installation.
2. The enclosure may be made of aluminum alloy and given a protective polyurethane
paint finish; however care should be taken to protect it from impact and abrasion when
located in Zone 0.
