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.

 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.

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
