Special Conditions for Hazardous Locations Use in Europe and

Internationally

The NI 9214 has been evaluated as Ex nA IIC T4 Gc equipment under DEMKO

Certificate No. 07 ATEX 0626664X and is IECEx UL 14.0089X certified. Each NI 9214 is

marked   II 3G and is suitable for use in Zone 2 hazardous locations, in ambient

temperatures of -40 °C ≤ Ta ≤ 70 °C. If you are using the NI 9214 in Gas Group IIC

hazardous locations, you must use the device in an NI chassis that has been

evaluated as Ex nC IIC T4, Ex IIC T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.

Caution

 You must make sure that transient disturbances do not exceed

140% of the rated voltage.

Caution

 The system shall only be used in an area of not more than

Pollution Degree 2, as defined in IEC 60664-1.

Caution

 The system shall be mounted in an ATEX/IECEx-certified

enclosure with a minimum ingress protection rating of at least IP54 as

defined in IEC/EN 60079-15.

Caution

 The enclosure must have a door or cover accessible only by the

use of a tool.
