Hazardous Area Considerations; Ex Safety Aspects And Ip Protection (Europe) - ABB JDF200 Operating Instruction

11 10 Hazardous Area considerations

11.1 10.1 Ex Safety aspects and IP Protection
(Europe)
According to ATEX Directive (European Directive 2014/34/UE of
26 February 2014) and relative European Standards which can
assure compliance with Essential Safety Requirements, i.e.,
EN 60079-0 (General requirements) EN 60079-1 (Flameproof
enclosures "d") EN 60079-11 (Equipment protection by intrinsic
safety "i") EN 60079-26 (Equipment with equipment protection
level -EPL- Ga) the field indicator 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.
a) Certificate 1G Ex ia IIC Tx Ga and II 1D Ex ia IIIC Tx Da IP67
INTERTEK Approvals certificate numbers
ITS 16 ATEX 10165X
IECEx ITS 16.0048X
The meaning of ATEX code is as follows:
— II : Group for surface areas (not mines)
— 1 : Category
— G : Gas (dangerous media)
— D: Dust (dangerous media)
— Tx°C: Maximum surface temperature of the transmitter
enclosure with a Ta (ambient temperature) +40°C for Dust
Application for field indicator Ex ia categories 1G and 1D
Application with Gas
Warning. When the equipment is used in zone 20, using only an application with type of protection Ex ta, it is necessary to limit the current
as indicated in the following table. In case of use together with an Ex ia application is not needed to limit the current.
For example the current can be limited with a fuse, as indicated in the table, installed in the control panel.

Important. The number close to the CE marking of the field
indicator safety label identifies the Notified Body which has
responsibility for the surveillance of the production.
The other marking refers to the protection type used according
to relevant EN standards:
— Ex ia: Intrinsic safety, protection level "Ga"
— IIC: Gas group
— T4: Temperature class of the field indicator
(corresponding to 135°C max) with a Ta from -50°C to +85°C
— T5: Temperature class of the field indicator
(corresponding to 100°C max) with a Ta from -50°C to +40°C
— T6: Temperature class of the field indicator
(corresponding to 85°C max) with a Ta from -50°C to +40°C
About the applications, this field indicator can be used in "Zone

Note: the protection is mainly
assured by the "IP" degree
associated to the low power
from supply. This can either be
[ia] or [ib] certified [Ex ia]
