c) Certificate ATEX II 3 G Ex ic IIC T4/T5/T6 Gc and II 3 D Ex tc IIIC T85°C Dc, Ta = -50°C to +75°C
FM Approvals Certificate number FM09ATEX0025X (Tremezzina, Warminster, Bangalore, Shanghai and Dammam products)
The meaning of ATEX code is as follows:
– II: Group for surface areas (not mines)
– 3: Category of equipment
– G: Gas (dangerous media)
– D: Dust (dangerous media)
– T85°C: Maximum surface temperature of the transmitter enclosure with a Ta from -50°C to +40°C for Dust (not Gas).
It is the technical support for the ABB Declaration of Conformity.
When installed this transmitter must be supplied by a voltage limiting device which will prevent the rated voltage of 42 V d.c. being
exceeded.
Certificate IECEx Ex ic IIC T4/T5/T6 Gc and Ex tc IIIC T85°C Dc, Ta = -50°C to +75°C
IECEx certificate number IECEx FME 16.0004X (Tremezzina, Warminster, Bangalore, Shanghai and Dammam products)
The other marking refers to the protection type used according to relevant EN standards:
– Ex ic: Intrinsic safety, protection level “c”
– IIC: gas group
– T4: Temperature class of the transmitter (which corresponds to 135°C max) with a Ta from -50°C to +85°C
– T5: Temperature class of the transmitter (which corresponds to 100°C max) with a Ta from -50°C to +40°C
– T6: Temperature class of the transmitter (which corresponds to 85°C max) with a Ta from -50°C to +40°C
– Ex tc: type of protection “tc” means protection by enclosure technique
About the applications, this transmitter can be used in Zone 2 (Gas) and in Zone 22 (Dust) (unlikely/infrequent hazard) .
Note for pressure transmitter with combined approval .
Before installation of the Transmitter, the customer should permanently mark his chosen Protection Concept on the safety label. The
transmitter can only be used with according to this Protection Concept for the whole life. If two or more types of protection box (on
safety label) are permanent marked, the pressure transmitter must be removed from hazardous classified locations. The selected Type
of Protection is allowed to be changed only by manufacturer after a new satisfactory assessment.
