Appendix 2 IECEx certification
A2.0 The IECEx Certification Scheme
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

A2.1 IECEx Certificate of Conformity
The BA317NE Tachometer has been issued with an
IECEx Certificate of Conformity number
IECEx ITS 16.0005X which specifies the following
certification code:
Ex nA ic IIC T5 Gc -40ºC ≤ Ta ≤ +60ºC
Ex ic tc IIIC T80ºC Dc IP66 ≤ Ta ≤ 60°C
The IECEx certificate may be downloaded from
www.beka.co.uk, www.iecex.com or requested from
the BEKA sales office.
The Tachometer'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, as shown on the IECEx
Certificate. This allows the Tachometer to be adjusted
and configured live when installed in a Ex n panel
enclosure located in Zone 2.
A2.2 Installation
The IECEx safety parameters are identical to the
ATEX safety parameters described in the main section
of this manual and both refer to equivalent standards.
Therefore the ATEX installation requirements specified
in the main sections and in Appendix 1 of this manual,
also apply for IECEx installations, but the local code of
practice should also be consulted.
For ATEX installations self certified Category 3GD
equipment, such as enclosures, may be installed in
Zone 2 or 22, but self certified equipment is not
permitted for IECEx installations.
A2.3 Special conditions for safe use
The IECEx certificate number has an ‘X’ suffix
indicating that special conditions apply for safe use.
These conditions are identical to the ATEX special
conditions for safe use specified in the main sections
and in Appendix 1 of this manual.
