## ¡ **Note when installing the EMI/EMC Filter on a DIN rail.** **When the EMI/EMC Filter is grounded through the DIN rail, the proper noise attenuation may not be achieved.** **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.** **==> picture [170 x 92] intentionally omitted <==** **----- Start of picture text -----**
