4.1. Mounting the Router
The router is fitted with a DIN-rail clip by default. To attach the router to a DIN-rail:
1. Position the router so that the spring of the DIN-clip rests on the DIN-rail.
2. Push the router in an upward direction so that the spring of the DIN-clip compresses and the top hook of
the DIN-clip slides and clamps to the DIN-rail.
To remove the router from the DIN-rail, simply reverse the procedure.
