BLADE OF PLUG TO WIDE SLOT, FULLY INSERT.
• This apparatus shall always be connected to a
AC outlet with a protective grounding
connection.
• To disconnect the apparatus from the mains,
the plug must be pulled out from the mains
socket, therefore the mains plug shall be
readily operable.
• Do not expose this apparatus to dripping or

Wiring the Main Power Supply
Plug (UK Only)
IMPORTANT NOTICE
The mains lead on this equipment is supplied with
a moulded plug incorporating a fuse. The value of
the fuse is indicated on the pin face of the plug
and if it requires replacing, a fuse approved to
BS1362 of the same rating must be used.
Never use the plug with the fuse cover removed.
If the cover is detachable and a replacement is
required, it must be of the same colour as the fuse
tted in the plug. Replacement covers are
available from your dealer. If the tted plug is not
suitable for the power points in your house or the
cable is not long enough to reach a power point,
you should obtain a suitable safety approved
extension lead or consult your dealer for assistance.

ENG - 3
However, if there is no alternative to cutting off the
plug, remove the fuse and then safely dispose of
the plug. Do not connect the plug to a mains
socket as there is a risk of shock hazard from the
bared exible cord. Never attempt to insert bare
wires directly into a mains socket. A plug and fuse
must be used at all times.
IMPORTANT
The wires in the mains lead are coloured in
accordance with the following code:– BLUE =
NEUTRAL BROWN = LIVE As these colours may not
correspond to the coloured markings identifying
the terminals in your plug, proceed as follows:– The
wire coloured BLUE must be connected to the
terminal marked with the letter N or coloured
BLUE or BLACK. The wire coloured BROWN must
be connected to the terminal marked with the
letter L or coloured BROWN or RED.
WARNING : DO NOT CONNECT EITHER WIRE TO
THE EARTH TERMINAL WHICH IS MARKED WITH
THE LETTER E OR BY THE EARTH SYMBOL ,
OR COLOURED GREEN OR GREEN AND YELLOW.
