IMPORTANT - Wiring Information (For U.K. only)
If the power cord supplied with this printer is not suitable for your electrical outlet, remove
the plug from the mains cord and fit an appropriate three pin plug. If the replacement plug is
intended to take a fuse then fit the same fuse as the original.
If a moulded plug is severed from the power cord then it should be destroyed because a plug
with cut wires is dangerous if plugged into a live socket outlet. Do not leave it where a child
might find it.
In the event of replacing the plug fuse, fit a fuse approved by ASTA to BS1362 with the same
rating as the original fuse.
Always replace the fuse cover. Never use a plug with the cover omitted.
WARNING - THIS PRINTER MUST BE PROPERLY EARTHED.
The wires in the mains cord are coloured in accordance with the following code:
Green and yellow:
Ground
Blue:
Neutral
Brown:
Live
The colours of the wiring in the power lead of this printer may not correspond with the
markings which identify the terminals in your plug. If you need to fit a different plug,
proceed as follows.
Remove a length of the cord outer sheath, taking care not to damage the coloured insulation
of the wires inside.
Cut each of the three wires to the appropriate length. If the construction of the plug permits,
leave the green and yellow wire longer than the others so that, in the event that the cord is
pulled out of the plug, the green and yellow wire will be the last to disconnect.
Remove a short section of the coloured insulation to expose the wires.
The wire which is coloured green and yellow must be connected to the terminal in the plug
which is marked with the letter “E” or by the earth symbol or coloured green or green and
yellow.
The wire which is coloured blue must be connected to the terminal which is marked with the
letter “N” or coloured black or blue.
The wire which is coloured brown must be connected to the terminal which is marked with
the letter “L” or coloured red or brown.
The outer sheath of the cord must be secured inside the plug. The coloured wires should not
hang out of the plug.
