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.
