Plug Fitting Instructions (U.K.) 

 
The power cord supplied with this product is factory fitted with a 13amp 

mains plug fitted with a 4.0 amp slo-blo fuse. If it is necessary to change 
the fuse it is important that a 4.0 amp slo-blo replacement fuse is used. If 
the plug needs to be changed because it is not suitable for your socket, or 

becomes damaged, it should be cut off and an appropriate plug fitted 
following the wiring instructions below. The unused plug should be 

disposed of safely as insertion into a 13amp socket is likely to cause an 
electrical hazard. Should it be necessary to fit a 3 pin BS mains plug to 
the power cord the wires should be connected as detailed below. The 

colours of the wires in the mains lead of this product may not correspond 
with the coloured markings identifying the terminals in your plug. Connect 
them as follows: 

 
The wire which is coloured BLUE must be connected to the terminal which 
is marked with the letter ‘N’ or coloured BLACK.
