## **Installation** 

FN 3025/FN 3026 are delivered with closed plastic covers and unfastened terminals. To install the filter please proceed as follows: 

Mount the filter on a metal surface with four screws or snap it onto a TS 35 DIN- rail.

First connect the green/yellow wire to the earth stud of the filter. 

Gently lift the two hinged plastic covers. Connect phase wires with cable lugs by pushing down and tightening the screws. Please note the torque recommendation on top of the filter. 

Push the covers back into their locked position to finish the filter installation.
