APPENDIX 1. SAFETY CERTIFICATION
The 1100A and 1100H analysers have been approved by various authorities for installation in
hazardous areas. The certification offered with a specific analyser will depend upon specification
and country of delivery. See the certification labels attached to the analyser for exact approval
details. The following information summarises the approvals that have been obtained.
If the analyser is installed in a hazardous area then electrical power and other connecting cables
should be installed and protected according to conditions on the relevant certificates, national
wiring regulations, hazardous area codes of practice and local authority regulations.
Analysers built to CENELEC standards also comply with the Swiss and Japanese standards.
