Installation Drawing: 9240 030-938.

Conditions of Certification

The intrinsically safe circuits do not withstand the 500V AC test as specified in EN 50020 clause 6.4.12.

Probes covered with plastic and/or with plastic discs will have a non-conducting area that exceeds the maximum permissible area for Group IIC accoring to IEC 60079-01 clause 7.3: 20 cm2 for Zone 1 and 4 cm2 for Zone 0. Therefore, when the probe is used in a potentially explosive atmosphere, appropriate measures must be taken to prevent electrostatic discharge.

Impact and friction hazards need then to be considered according to IEC 60079-0 clause 8.1.2 when the transmitter exposed to the exterior atmosphere of the tank is made with light metal alloys and used in Zone 0.

(1)Other temperature restrictions may apply, please refer to “Specifications” on page A-1.
