How to use

Mount the insert into the prepared wall box and secure it behind the selected JUNG frame or faceplate according to the installation guidance provided by the frame manufacturer. Connect the supply and load conductors to the screw terminals, ensuring proper tightening and correct wiring polarity where applicable. Verify mechanical operation of the actuator and restore power to test switching of the connected circuit.

Recommendations
