Appendix 12 EMC AND LOW VOLTAGE DIRECTIVE
Appendix 12.1 Requirements for Conformance to EMC Directive
(1) Standards applicable to the EMC Directive
The standards applicable to the EMC Directive are listed below.
All test items were tested by installing each device on a personal computer bearing a
CE certification logo.
(a) Emission requirements
*1: The tests were conducted installed in a control panel.
*2: QP: Quasi-peak value, Mean: Average value
(b) Immunity requirements
*1: The tests were conducted installed in a control panel.
