When using the micro controller in an area where the imposed noise level is expected to exceed 1000V, we recommend using
a noise filter on the master side as seen in the figure below.
[Noise filter] (recommended): ZRAC2203-11 (made by TDK Corporation)
•
If there are problems with EMC during communication, the noise level can be reduced by using a communication cable with a
ferrite core.
Ferrite core (recommended): ZCAT series (made by TDK Corporation)
MSFC series (made by Morimiya Electric Co., Ltd.)
