Appendix A. CE Mark compliance and high noise
environments
A.1 Introduction
For CE Mark compliance, the PanaFlow Z1G/Z2G Process Gas
Flowmeter must meet the EMC and LVD directives.
Attention European Customers!
CE Mark compliance is required for all units
intended for use in EU countries, and it is
also recommended for installation in high
electrical noise environments.
A.2 EMC compliance
In addition to the standard wiring requirements, the
electrical connections must be shielded and grounded as
described in Table 11 below for EMC compliance. After all the
necessary electrical connections have been made, seal any
unused cable entry holes.
Note: If the instructions in this appendix are followed, the
unit will comply with the EMC Directive.
