Setup and Installation
The Märklin 74462 digital decoder is designed for straightforward installation without the need for specialized tools or extensive knowledge. It is compatible with all Märklin C-track switches that feature an electric drive.
- Prepare the Turnout: Ensure your C-track turnout is equipped with an electric drive. Disconnect power from your model railway system before proceeding.
- Locate Connection Points: The decoder connects via plug contacts. Identify the corresponding connection points on your C-track turnout's electric drive.
- Connect the Decoder: Simply plug the decoder into the designated contacts. The design ensures a secure and correct connection.
- Power Supply: The digital power supply for the decoder can be taken directly from the contact of the switch to the contact with the current. This integrates the decoder seamlessly into your digital track system.

The decoder can be installed either at the same time as the electric drive or retrofitted later.
