Procedure:
1. Connect the connection cable to the remote terminal (see the manual from manufacturer). Trim
the unneeded insulated conductors up to the cable shield and note down the conductor colors.
2. Connect the connection cable to the six-pole plug:
• Depending on the remote terminal and the pin assignment of the desired pin group,
identify the conductor entries that are required for connecting the connection cable.
• Release the required conductor entries using a screwdriver and insert the insulated
conductors into the conductor entries. Observe the pin assignment.
3. Insert the six-pole plug into pin row A in terminal X2.
4. On the connection cable, mark the terminal and the pin row to which the connection cable is
assigned. Use the supplied cable tie with caption field.
5. Write down the terminal assignment on the supplied supplementary sheet.
