APPENDIX 3
IECEx gas and dust certification
IECEx is a global certification scheme for explosion
protected products which aims to harmonise
international certification standards. For additional
information about the IECEx certification scheme
and to view the BEKA associate certificates, please
visit www.iecex.com
A3.1 IECEx Certificate of Conformity
The BA307NE and the BA327NE loop powered
indicators and the optional accessories have been
issued with an IECEx Certificate of Conformity
number IECEx ITS 14.0026X that specifies the
following certification codes:
Ex nA ic IIC T5 Gc
Ex tc IIIC T80°C Dc IP66
Ta = -40°C to 70°C
The specified gas and dust safety parameters are
identical to the ATEX safety parameters described
in the main section and Appendix 1 and 2 of this
manual.
The IECEx certificate may be downloaded from the
BEKA associates website www.beka.co.uk, from
the IECEx website www.iecex.com or requested
from the BEKA sales office.
A3.2 Installation
The IECEx and ATEX certificates specify identical
safety parameters and installation requirements for
both indicators. The ATEX installation
requirements specified in the main section of this
manual and in Appendix 1 & 2 may therefore be
used for IECEx installations which should comply
with IEC 60079-14
Electrical installations design,
selection and erection
. The local code of practice
should also be consulted.
APPENDIX 4
ETL & cETL certification for installations in
USA and Canada.
A4.0 cETL Mark
For installations in the USA and Canada, the
BA307NE and BA327NE indicators have ETL and
cETL Ex nA and Ex tc approval, Control Number
4008610. Copies of the Authorisation to Mark may
be downloaded from the BEKA associates website
www.beka.co.uk
or requested from the BEKA
associates sales office
A4.1 ETL and cETL certification
The US and Canadian standards used for
assessment and certification of the BA307NE and
BA327NE are listed on the cETL Authorisation to
Mark.
ETL codes for USA
Class I Zone 2 AEx nA ic IIC T5 Gc
Zone 22 AEx ic tc IIIC T80ºC Dc

cETL codes for Canada
Ex nA ic IIC T5 Gc
Ex n IIC T5 Gc
Ex ic tc IIIC T80ºC Dc
Class III Div 2 Class II Div 2 Gp F G
Ta = -40°C to 60°C
The ETL and cETL safety parameters are the
same as the ATEX and IECEx parameters,
therefore the systems shown in the main section of
this manual and in Appendix 1 may be used for US
and Canadian installations subject to complying
with the local codes of practice.
The Indicator's front panel push button contacts
are non incendive and have been certified
intrinsically safe Ex ic, without the need for an
external Zener barrier or galvanic isolator. This is
the 'ic' code shown on the instrument's certification
label and on the ETL Authorisation to Mark. This
allows the loop powered indicator to be adjusted
and configured live when installed in a Zone 2 or
22 hazardous areas. These loop powered
indicators are not intrinsically safe and therefore
external Zener barriers or galvanic isolators are not
required.
