Special Conditions for Safe Use (X):
1. Appropriate ex d blanking plugs, cable glands, and wiring needs to be suitable for a
temperature of 90 °C.
2. This 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.
