DIN rail
Note when installing the EMI/EMC
¡
Filter on a DIN rail.
DIN rail
When the EMI/EMC Filter is grounded through
the DIN rail, the proper noise attenuation may not
be achieved.
Name Plate
Be sure to connect the protection earth (PE) of
the EMI/EMC Filter body to the earth.
It can connect the ground to either one only.
