Make sure that only fuses with the required rated current and of the specified type are used for
replacement. The use of makeshift fuses and the short-circuiting of fuse holders is prohibited.
Mains Lead
When a three core mains lead with bare ends is provided this should be connected as follows:
BROWN
BLUE
GREEN/YELLOW
When fitting a fused plug a 5amp fuse should be fitted inside the plug. As the colours of the wires
in the mains lead of this apparatus 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 unit is to be connected to the main supply by fixed wiring, rather than via an AC line plug,
then the protective earth (ground) wire in the 3 core mains lead shall be connected to a protective
conductor before any other connection is made.
Any interruption of the protective conductor inside or outside the apparatus or disconnection of
the protective earth terminal is likely to make the apparatus dangerous. Intentional interruption is
prohibited.
