CE Mark Compliance B-1
September 2004
Introduction For CE Mark compliance, the Model AT868 flow transmitter must
meet both the EMC and LVD directives.
IMPORTANT: CE Mark compliance is required only for units
intended for use in EEC countries.
EMC Compliance For EMC compliance, the electrical connections must be shielded and
grounded as in Table B-1 below. Also refer to Figures B-1 and B-2 on
the next page for illustrations of wiring. After all the necessary
electrical connections have been made, seal any unused cable entry
holes with standard conduit plugs or equivalent.
Note: If the instructions in this appendix are followed, the unit will
comply with the EMC Directive 89/336/EEC.
