IMPORTANT SAFETY WARNINGS
THIS UNIT MUST BE EARTHED
Under no circumstances should the mains earth be disconnected from the mains
lead.
The wires in the mains lead are coloured in accordance with the following code:
Earth: Green and Yellow (Green/Yellow - US)
Neutral: Blue (White - US)
Live: Brown (Black - US)
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 codings are followed carefully in the event of the plug being changed.
To avoid the risk of fire, replace the mains fuse only with the correct value fuse,
as marked on the rear panel.
The internal power supply unit contains no user serviceable parts. Refer all
servicing to a qualified service engineer, through the appropriate Soundcraft
dealer.
