APPENDICES
A
Appendix 7 EMC and Low Voltage Directives
Appendix 7.1 Measures to comply with the EMC Directive
(b) Immunity requirements
*1 The module is an open type device (a device designed to be housed in other equipment) and must be installed inside a
conductive control panel. The tests were conducted with the programmable controller installed in a control panel.
*2 The accuracy of an analog-digital converter module may temporarily vary within ±10%.
