WARNING: THE COMPUTER MUST BE EARTHED Important: The wires in the mains lead to the computer are coloured in accordance with the following code: Green and yellow Earth Blue Neutral Brown Live As the colours of the wires may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The wire which is coloured green and yellow must be connected to the terminal in the plug which is marked by the letter E, or by the safety earth symbol or coloured green, or green and yellow. The wire which is coloured blue must be connected to the terminal which is marked with the letter N, or coloured black.
The wire which is coloured brown must be connected to the terminal which is marked with the letter L, or coloured red. If the socket outlet available is not suitable for the plug supplied, the plug should be cut off and the appropriate plug fitted and wired as previously noted. The moulded plug which was cut off should be disposed of as it could be a potential shock hazard if it were to be plugged in with the cut off end of the mains cord exposed. The moulded plug must be used with the fuse and fuse carrier firmly in place. The fuse carrier is of the same basic colour* as the coloured insert in the base of the plug. Different manufacturers’ plugs and fuse carriers are not interchangeable.
In the event of loss of the fuse carrier, the moulded plug MUST NOT be used. Either replace the moulded plug with another conventional plug wired as previously described, or obtain a replacement fuse carrier from an authorised BBC Microcomputer dealer. In the event of the fuse blowing it should be replaced, after clearing any faults, with a 3 amp fuse that is ASTA approved to BS1362. *Not necessarily the same shade of that colour. Exposure Like all electronic equipment, the BBC Microcomputer should not be exposed to direct sunlight or moisture for long periods.
