IMPORTANT INFORMATION FOR UK CUSTOMERS

DO NOT

cut off the mains plug from this equipment. If the plug fitted is not suitable for the power points in your home or the cable

is too short to reach a power point, then obtain an appropriate safety approved extension lead or consult your dealer. If, nonetheless,

the mains plug is cut off, REMOVE THE FUSE and dispose of the PLUG immediately, to avoid possible shock hazard by inadvertent

connection to the mains supply. If this product is not provided with a mains plug, or one has to be fitted, then follow the instructions

given below:

IMPORTANT

DO NOT

make any connection to the larger terminal which is marked with the letter ‘E’ or by the safety

earth symbol or coloured GREEN or GREEN AND YELLOW.

The wires in the mains lead on this product are coloured in accordance with the following code:

BLUE - NEUTRAL

BROWN - LIVE

As these colours may not correspond with the coloured markings identifiying the terminals in your plug, proceed as follows:

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

The BROWN wire must be connected to the terminal marked with the letter ‘L’ or coloured RED

When replacing the fuse, only a correctly rated and approved type should be used, and be sure

to re-fit the fuse cover.
