6.5 Inserting and routing the cables
Insert the cable into the terminal box
Proceed as follows when introducing cables into the terminal box:
1. Unscrew the cable entry plate.
2. Drill the required number of holes or threads in the required size in the cable entry plate.
3. Fit the required cable glands.
4. Route the cables through the cable glands.
5. Fit the cable entry plate to the terminal box with the assembled cables.
6. Connect the ends of the cables to the terminals in accordance with the circuit diagram. The
