Appendix 3 ETL & cETL certification for
installations in USA and Canada
A3.0 cETL Mark
For installations in the USA and Canada, the
BA367NE Counter has ETL and cETL Ex nA and
Ex tc approval, Control Number 4008610. Copies
of the Authorisation to Mark are available from the
BEKA associates sales office and www.beka.co.uk
A3.1 ETL and cETL certification
The US and Canadian standards used for
assessment and certification of the BA367E are
listed on the cETL Authorisation to Mark.
Installations must comply with BEKA associates
Control Drawing CI330-53, which is attached to this
appendix.
The ETL and cETL safety parameters are the same
as the ATEX and IECEx parameters, the systems
shown in sections 3, 4 and 5 of this manual may
therefore also be used for US and Canadian
installations subject to complying with the local
codes of practice.

The Counter'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 ETL
Authorisation to Mark. This allows the Counter to be
adjusted and configured live when installed in a Ex n
panel enclosure located in Zone 2.
