2600T Series Pressure transmitters | SOI/266-XC Rev. I 197 Hazardous area considerationsAccording to ATEX Directive (European Directive 94/9/EC of 23 March1994) and relative Standards which can assure compliance withEssential Safety Requirements, i.e., EN 60079-0 (Generalrequirements) EN 60079-15 (Specification for electrical apparatus withtype of protection “n”) EN 61241-0 (General requirements), thepressure transmitters of the 2600T SERIES have been certified for thefollowing group, categories, media of dangerous atmosphere,temperature classes, types of protection. Examples of application arealso shown below by simple sketches.d) Certificate ATEX II 3 G Ex nL IIC T4/T5/T6(for T4 = -50°C ≤ Ta ≤+85°C),(for T5 and T6 = -50°C ≤ Ta ≤+40°C) and II 3D Ex tD A22 IP67 T85°C.FM Approvals Certificate numberFM09ATEX0025X (Lenno products)FM09ATEX0070X (Minden products)FM11ATEX0037X (Faridabad products)FM11ATEX0048X (Shanghai products)The meaning of Atex code is as follows :− II 3G Ex nL IIC T4/T5/T6 (for T4 = -50°C < Ta < +85°C) (for T5and T6 = -50°C < Ta < +40°C)− II: Group for surface areas (not mines)− 3: Category of equipment− G: Gas (Dangerous media)− Ex nL: type of protection “n” with “energy limitation” technique− IIC: gas group− T4: Temperature class of the transmitter (which corresponds to135°C max) with a Ta from -50°C to +85°C− T5: Temperature class of the transmitter (which corresponds to100°C max) with a Ta from -50°C to +40°C− T6: Temperature class of the transmitter (which corresponds to85°C max) with a Ta from -50°C to +40°CApplication with Gas Application with DustNote: the transmitter must beconnected to a supply with 42Vd.c. max output voltage asabove indicated. The Ii of thetransmitter is less than 25 mA.Zone 2266 Tx Category 3G Ex nLNote: the protection is mainlyassured by the “IP” degreeassociated to the low powerfrom supply.Important - Note for pressure transmitter with combined approval. Before installation of the Transmitter, the customer should permanent mark hischosen Protection Concept on the safety label. The transmitter can only be used with according to this Protection Concept for the whole life. If twoor more types of protection box (on safety label) are permanent marked, the pressure transmitter must be removed from hazardous classifiedlocations. The selected Type of Protection is allowed to be changed only by manufacturer after a new satisfactory assessment.Important. It is the technical support for the ABB Declaration ofConformityImportant. When installed this transmitter must be supplied by a voltagelimiting device which will prevent the rated voltage of 42 V d.c. beingexceeded.About the applications, this transmitter can be used in Zone 2 (Gas)(unlikely/infrequent hazard) as it shown on the following skecth (leftside)− II 3D Ex tD A22 IP67 T85°C− II: Group for surface areas (not mines)− 3: Category of equipment− D: Gas (Dangerous media)− Ex tD: type of protection “tD” means protection by enclosuretechnique− A22: for zone 22 (tested acc. to method A of EN61241-0)− IP67: degree of protection of the transmitter acc.
