  • Page 48: Appendix 1. Ce Marking

    APPENDIX 1. CE MARKING EZA-MAPRB conforms to EMC directive. The low voltage directive is out of the range because EZA-MAPRB is activated by 24VDC power supply. APPENDIX 1-1. EMC Directives It is necessary to do CE marking in the customer’s responsibility in the state of a final product. Confirm EMC compliance of the machine and the entire device by customer because EMC changes configuration of the control panel, wiring, and layout.
