Appendix 9.2 Emc Directives - Mitsubishi Electric MELDAS C6 Maintenance Manual

Appendix 9.2 EMC Directives

The EMC Directives largely regulate the following two items.
• Emission ..... Capacity to prevent output of obstructive noise that adversely affects external devices.
• Immunity ..... Capacity not to malfunction due to obstructive noise from external source.
The details of each level are classified below in Table 1.
It is assumed that the Standards and test details required for a machine tool are the same as these.
