Hinweis zum Einbau

  • Depending on installation position reduced maximum forces are to be expected at an opening width from 500mm
  • CDi/600-800: For stroke lengths from 600 mm and using the maximum permissible force the ventilation operation can be reduced to a operational life of approx. 10,000 cycles.
  • Before the cable strands are cut and terminated into the 8-pole plug the lower plug housing must be pulled over the cable.
  • please order cable sets separately)
