Precautions for mounting DIN rail

Grounding through a DIN rail may not provide the proper noise attenuation effect.
Grounding should be done by connecting to the protective ground terminal (PE) of the noise filter main body.
There are 2 protective ground terminals, but you can use it even by connecting only one of them.
