4. Electrical Connection
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.
Earth Symbol
Double Insulated Symbol
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.
