When using the instrument in the United Kingdom,
make sure the power cord meets the following safety
instructions.
NOTE: This lead/appliance must only be wired by
competent persons.
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in
accordance with the following code:
As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed as
follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal
marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or
contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable of
0.75mm2 should be protected by a 3A or 5A fuse. Larger conductors
would normally require 13A types, depending on the connection
method used.
Any exposed wiring from a cable, plug or connection that is engaged
in a live socket is extremely hazardous. If a cable or plug is deemed
hazardous, turn off the mains power and remove the cable, any
fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.
