• The mains supply disconnect device is the mains plug. It must remain
accessible so as to be readily operable when the apparatus is in use.
• If any part of the mains cord set is damaged, the complete cord set should
be replaced. The following information is for reference only. The wires
in the mains lead are coloured in accordance with the following code:
• Protective Earth (Ground): Green/Yellow (US: Green or Green/
Yellow)
• Neutral: Blue (US: White)

As the colours of the wires in the mains lead may not correspond with
the coloured markings identifying the terminals in your plug, proceed
as follows:
• 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.
• The wire which is coloured Blue must be connected to the terminal in
the plug which is marked with the letter N
• The wire which is coloured Brown must be connected to the terminal
in the plug which is marked with the letter L
Ensure that these colour codes are followed carefully in the event of the
