4. Identyfikuj terminale: The HBL2721 plug has four terminals: three for the phase conductors (L1, L2, L3) and one for the ground conductor (G). Refer to the internal markings for correct identification.
5. Podłącz przewody:
   • Connect the ground wire (typically green or bare copper) to the grounding terminal (G).
   • Connect the three phase wires (L1, L2, L3, typically black, red, blue/brown, orange, yellow) to their respective phase terminals. Ensure proper phase rotation if critical for your application.
   Ensure all wire strands are captured under the terminal screws and tighten securely. Do not overtighten.
6. Sprawdź połączenia: Double-check all connections for tightness and ensure no stray wire strands are present that could cause a short circuit.
