Appendix 8 EMC and Low Voltage Directives
Appendix 8.1 Requirements for compliance with the EMC Directive
(2) Regulations regarding immunity
*1: Programmable controllers are open-type devices (devices designed to be housed inside other equipment) and must be
installed inside a conductive control panel. The corresponding tests were conducted with the programmable controller
installed inside a control panel.
*2 The accuracy of an analog-digital converter module may temporary vary within ±10%.
