16. Electrical Connection and 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 and 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. After inserting the plug into the socket, protection must be
provided so that the combination of BS plug and socket will have an IP
degree of at least IP44. 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:
Installation requirement for electrical system:
Electrical system providing a RCD with a maximum residual current of 0.03A
should be provided. Installation of over voltage protection is needed.
Steady state voltage: 0.9-1.1 of nominal voltage (230V~).
Frequency: 0.99-1.01 of nominal frequency continuously; 0.98-1.02 short
time.
HVF: ≤0.02
Site Operating Conditions
a. Altitude are not exceeding 1000m,
b. Maximum ambient air temperature is +40 ºC, minimum ambient air
temperature is not less than 0 ºC,
c. Storage and transportation temperature range is -15ºC~40ºC.
d. The relative humidity does not exceed 50% at a maximum temperature of
+40ºC, higher relative humidity may be permitted at lower temperature
(e.g. 90%@ 20ºC).
e. The machine can be stored or transported under ambient temperatures
between -25ºC and +55ºC.
Through poor conditions of the electrical MAINS, shortly voltage drops can
appear when starting the EQUIPMENT. This can influence other equipment
(e.g. Blinking of a lamp). If the MAINS-IMPEDANCE Zmax<0.252OHM, such
disturbances are not expected. (In case of need, you may contact your local
supply authority for further information).
Before the machine is connected in TN-S power supply system, the end user
shall perform the test according to clause 18.2 of EN 60204-1.
If in doubt about the connection of the electrical supply, always consult a
qualified electrician.
