9.1.7  MICROMASTER 411 – EMC Compliance 
The MICROMASTER 411 inverters will, when correctly installed and put to their 
intended use, satisfy the requirements of the EEC Directive 89/336/EEC 
concerning electromagnetic compatibility. 
If the guidelines on installation to reduce the effects of electromagnetic interference 
are followed, the devices are sutiable for installation in machines. According to the 
machinery directive, these machines must be separately certified. 
Table 9-5 below lists the measured results for emissions of an immunity to 
interference for the MICROMASTER 411 inverters.
