  3. Remove the cover from the communication connection area.
  4. Remove the swivel nut from one of the cable glands for the communication cable.
  5. Thread the union nut over the signal cable.
  6. Remove the two-hole cable support sleeve from the cable gland. As required, use the cable support sleeve for a cable diameter of between 4.5 mm to 6 mm or between 6 mm to 8 mm that is included in the scope of delivery.
  7. Remove the sealing plug from one of the enclosure openings of the two-hole cable support sleeve and insert the cable into the enclosure opening.
  8. Strip off a maximum of 6 mm of the cable insulation.
  9. Unlock the conductor inserts on the provided 6-pole connector by loosening the screw.
  10. Connect the conductors of the connection cable to the supplied 6-pole connector. To do so, plug the conductors into the conductor entries and close the conductor entries by tightening the screws. Observe the connector assignment.
  11. Plug the 6-pole connector into the port DI: D1-D4, Vcc on the product. Observe the pin assignment.
  12. Ensure that the connector is securely in place.
  13. Ensure that all conductors are correctly connected.
  14. Ensure that the conductors sit securely in the terminal points.
