îš„EMC Directive
Varispeed F7-Series Inverters satisfy testing for conformance to the EMC Directive under the conditions
described in European Standard EN61800-3.
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.
• To suppress harmonics, install a DC reactor in CIMR-F7A20P4, 20P7, 40P4, and 40P7 models. (Refer to
Table 10.6 DC Reactors for Suppressing Harmonics.)
