Appendix 2 ETL & cETL certification for
installations in USA and Canada
A2.0 cETL Mark
For installations in the USA and Canada, the
BA377E Timer or Clock has ETL and cETL intrinsic
safety and nonincendive approval, Control Number
4008610. Copies of the Authorisation to Mark are
available from the BEKA associates sales office and
www.beka.co.uk
A2.1 Intrinsic safety approval
The US and Canadian standards used for
assessment and certification of the BA377E are
listed on the cETL Authorisation to Mark.
Installations must comply with BEKA associates
Control Drawing CI330-52, which is attached to this
appendix.
The ETL safety parameters are the same as the
ATEX and IECEx parameters, the systems shown in
sections 2 and 3 of this manual may therefore also
be used for US and Canadian installations subject to
compliance with the local codes of practice.
