WARNING: THE Z80 SECOND PROCESSOR MUST BE EARTHED
Important: The wires in the mains lead for the. Z80 second processor 
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 ye11ow must be connected to the 
terminal  in  the  plug  which  is  marked  by  the  letter  E,  or  by  the 
safety earth symbol 4 or coloured green, or green and ye11ow.
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  must  be-
disposed of as it would 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.
