10 Hazardous area considerations
According to ATEX Directive (European Directive 2014/34/UE of
26 February 2014) and relative Standards which can assure
compliance with Essential Safety Requirements, i.e., EN 60079-0
(General requirements) EN 60079-11 (Specification for electrical
apparatus with type of protection “n”) JDF200 has been certified
for the following group, categories, media of dangerous
atmosphere, temperature classes, types of protection. Examples
of application are also shown below by simple sketches.
d) Certificate ATEX II 3G Ex nA IIC Tx Gc and II 3G Ex ic IIC Tx Gc
and II 3D Ex tc IIIC Tx Dc IP67
ITS 16 ATEX 10166X
IECEx ITS 16.0048X
The meaning of Atex code is as follows :
— II 3G Ex nA IIC T4/T5/T6 (for T4 = -50°C < Ta < +85°C)
(for T5 and T6 = -50°C < Ta < +40°C)
— II: Group for surface areas (not mines)
— 3: Category of equipment
— G: Gas (Dangerous media)
— Ex nA: type of protection “n” with “No Sparking” technique
— Ex ic: type of protection “n” with “No Sparking” technique
— IIC: gas group
— Tx: Temperature class of the transmitter (which
corresponds to 135°C max) with a Ta from -50°C to +85°C
Important. It is the technical support for the ABB Declaration of
Conformity
Application with Gas
Application with Dust
Note: the field indicator must
be connected to a supply with
42V d.c. max output voltage
as above indicated. The Imax
of the field indicator is shown
in chart 10.1.2 “Entities for Ex
D and Ex nA”.
Zone 2
JDF200 Category 3G Ex nA
Note: the protection is mainly
assured by the “IP” degree
associated to the low power
from supply.
Important - Note for field indicator with combined approval. Before installation of the field indicator, the customer should permanent
mark his chosen Protection Concept on the safety label. The field indicator 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 field indicator 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.
Important. When installed this field indicator must be supplied by a
voltage limiting device which will prevent the rated voltage of 42 V
d.c. being exceeded.
About the applications, this field indicator can be used in Zone 2
(Gas) (unlikely/infrequent hazard) as it shown on the following
skecth (left side)
— II 3D Ex tc IIIC Tx Dc IP67
— II: Group for surface areas (not mines)
— 3: Category of equipment
— D: Dust (Dangerous media)
— Ex tc: type of protection “tc” means protection by enclosure
technique
— IIIC: for Dust application
— Tx: Temperature class of the transmitter
— Dc: Energy Protection Level
— IP67: degree of protection of the transmitter acc. EN60079
About the applications, this transmitter can be used in Zone 22
(Dust) (unlikely/infrequent hazard) as it shown on the following
