WARNING! Read these electrical safety instructions thoroughly
before connecting the product to the mains supply.
Before switching the product on, make sure that the voltage of your electricity supply is
the same as that indicated on the rating plate. This product is designed to operate on
230VAC 50Hz. Connecting it to any other power supply may cause damage.
This product may be fitted with a non-rewireable plug. If it is necessary to change the
fuse in the plug, the fuse cover must be refitted. If the fuse cover becomes lost or
damaged, the plug must not be used until a suitable replacement is obtained.
If the plug has to be changed because it is not suitable for your socket, or due to
damage, it should be cut off and a replacement fitted, following the wiring instructions
shown below. The old plug must be disposed of safely, as insertion into a mains socket
could cause an electrical hazard.
WARNING! The wires in the power cable of this product are
coloured in accordance with the following code:
Blue = Neutral Brown = Live Yellow and Green = Earth
If the colours of the wires in the power cable of this product do not correspond with the
markings on the terminals of your plug, proceed as follows.
• The wire which is coloured Blue must be connected to the terminal which is
marked N or coloured Black.
• The wire which is coloured Brown must be connected to the terminal which is
marked L or coloured Red.
• The wire which is coloured Yellow and Green must be connected to the
terminal which is marked E or or coloured Green.
We strongly recommend that this machine is connected to the mains supply via a
Residual Current Device (RCD)
If in any doubt, consult a qualified electrician. DO NOT attempt any repairs yourself.
