Ordinary 3-wire cable with a common sheath will not fit through the cable entry of this connector.
Instead, only two or three individual single-core cables with a conductor cross-section of between 10 and 16 mm² will fit.
The total diameter of a single-core 16 mm² cable is approx. 7 mm.
At the end of the connector, the 2 or 3 single-core cables are routed side by side through a strain relief.
When using 2 single-core cables, these should not exceed a total diameter of approx. 9 mm, when connecting 3 cables, only 7.1 mm each, as the cables will lie directly next to each other in the 21.5 mm wide strain relief.
The cables are fed into the connector through a thin flexible seal. The seal already has openings for 2 wires. If a third wire is to be connected, the seal must be pierced at the marked point with a pointed tool.

Don't worry, it will fit! The cable entry of this plug does not accept an ordinary 3-core cable with a common sheath. Instead, only two or three individual single-core cables between 10 to 16 mm² conductor cross-section will fit. The total diameter of a single-core 16 mm² cable is approx. 7 mm. At the end of the plug, the 2 or 3 single-core cables are guided through an 21.5 mm wide strain relief. When using two single-core cables, the two cables may each have a total diameter of approx. 9 mm. If the plug is to be fitted with 3 single-core cables, cables will lay side by side. That is why the total diameter of the individual cables must not exceed 7.5 mm.
