9. Electrical Connection & Wiring Diagram
Machines supplied for use in the UK are fitted with a 3 pin
plug conforming to BS1363, fitted with a fuse conforming
to BS1362 and appropriate to the current rating of
the machine.
Machines supplied for use in other countries within
the European Union are fitted with a 2 pin Schuko plug
conforming to CEE 7/7.
Machines supplied for use in Australia & New Zealand are
fitted with a 3 pin plug conforming to AS/NZS3112.
In all cases, if the original plug or connector has to be
replaced for any reason, the wires within the mains power
cable are colour coded as follows:
230 V (Single Phase)
Brown:
Live (L)
Blue:
Neutral (N)
Green and Yellow: Earth (E)
The wire coloured brown must always be connected to the
terminal marked ‘L’ or coloured red.
The wire coloured blue must always be connected to the
terminal marked ‘N’ or coloured black.
The wire coloured green and yellow must always be
connected to the terminal marked ‘E’ or with the
earth symbol:
or coloured green / green and yellow.
It is important that the machine is effectively earthed. Some
machines will be clearly marked with the double
insulated logo:
In this case there will not be an earth wire within
the circuit.
In the case of the BS1363 plug for use in the UK, always
ensure that it is fitted with a fuse conforming to BS1362
appropriate to the rating of the machine. If replacing the
original fuse, always fit a fuse of equivalent rating to the
original. Never fit a fuse of a higher rating than the original.
Never modify the fuse or fuse holder to accept fuses of a
different type or size.
Where the current rating of the machine exceeds 13 A at
230 V, or if the machine is designated for use on a 400 V 3
phase supply a connector conforming to BS4343 (CEE17 /
IEC60309) will be used.
230 V machines will be fitted with a blue 3 pin connector.
The wiring for this type of this connector will be the same
as shown above.
400 V, 3 phase machines will be fitted with a red 4 or 5 pin
connector. The wiring for this type of connector is as
shown below:
400 V (3 phase)
Brown:
Live (L1)
Black:
Live (L2)
Grey:
Live (L 3)
Blue:
Neutral (N)
Green and Yellow: Earth (E)
The wire coloured brown must always be connected to the
terminal marked ‘L1’.
The wire coloured black must always be fitted to the
terminal marked ‘L2’.
The wire coloured grey must always be connected to the
terminal marked ‘L3’.
The wire coloured blue must always be connected to the
terminal marked ‘N’ or coloured black.
The wire coloured green and yellow must always be
connected to the terminal marked ‘E’ or with the earth
symbol. If in doubt about the connection of the electrical
supply, always consult a qualified electrician.
