EMC Directive
Varispeed G7-Series Inverters satisfy testing for conformance to the EMC Directive under the conditions
described in European Standard EN61800-3:2004+A1:2012.
Installation Method
In order to ensure that the machinery or installation incorporating the Inverter conforms to the EMC Directive,
perform installation according to the method below.
Install a noise filter that conforms to European Standards on the input side. (Refer to Table 10.5 EMC
•
Noise Filters).
Use a shielded line or metal piping for wiring between the Inverter and Motor. Make the wiring as short as
•
possible.
