9.1.2 Measures to satisfy the EMC directive

Concrete measures for EMC directive of CE markings are shown below.
Models with a built-in EMC filter
(1) 200V class: VFAS1-2004PL~2075PL
400V class: VFAS1-4007PL~4500KPC
The above mentioned models install EMC noise filter inside. So the conducted and radiated noise can be reduced,
optional EMC noise filters are not needed.
(If a further noise reduction is required, insert an additional filter described in I-4 on the input side of the inverter.)
