Twist the exposed wire of each conductor with your fingers to ensure a secure grip before inserting and securing each into the three terminals as follows: blue to N, brown to L, and green/yellow to E.
Next, tighten the cord grip while ensuring the grip is secured against the complete outer white covering of the cord. The grip should not be secured directly on the exposed coloured conductors. Extreme care must be taken at this point as failure to ensure the grip is secure may result in a future accident. Replace the outer cover of the plug and secure it in place with the screw.
