Some models have a voltage selector switch for
compatibility with power systems around the world.
Before you plug in such a model, make sure that the
voltage selector is set to the correct voltage for your
area.

supply cord of this unit should be performed only by
qualified service personnel.
IMPORTANT
The wires in the mains lead are coloured in accordance
with the following code:
Blue: Neutral
Brown: Live
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 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.
IMPORTANT
The plug is fitted with an appropriate fuse. If the fuse
needs to be replaced, the replacement fuse must
approved by ASTA or BSI to BS1362 and have the
same ampere rating as that indicated on the plug. Check
for the ASTA mark or the BSI mark on the body of the
fuse.
If the power cord’s plug is not suitable for your socket
outlets, cut it off and fit a suitable plug. Fit a suitable
fuse in the plug.
