\uD83C\uDF31 Solution
replace old IEC modul with new one. New one comes with new UTP cable which must be replaced also! Part number H-1013 IEC module with housing
Attached document to new part is available here.
DO NOT USE other cable, because it will damage the IEC modul or other components in the station.
