• Should your mains plug need replacing and you are competent to do this, proceed as instructed below. If you are in doubt, contact an Elu authorized repair agent or a qualified electrician.
• Disconnect the plug from the supply.
• Cut off the plug and dispose of it safely; a plug with bared copper conductors is dangerous if engaged in a live socket outlet.
• Only fit 13 Amperes BS1363A approved plugs fitted with the correctly rated fuse (1).
• The cable wire colours, or a letter, will be marked at the connection points of most good quality plugs. Attach the wires to their respective points in the plug (see below). Brown is for Live (L) (2) and Blue is for Neutral (N) (4).
• Before replacing the top cover of the mains plug ensure that the cable restraint (3) is holding the outer sheath of the cable firmly and that the two leads are correctly fixed at the terminal screws.
