IMPORTANT SAFEGUARDS
For your own safety read following instructions carefully before attempting to connect this
Amplifier to the mains.
Mains Supply: 230V ~ 50Hz - AC only
This unit is designed to operate on a 230V~50Hz supply only. Connecting it to other power
sources may damage it. Ensure that the supply corresponds to the information on the rating
label on the bottom of the Amplifier.
This component system may be fitted with a non-rewireable plug. If it is necessary to change the fuse
in a non-rewireable plug the fuse cover must be refitted. If the fuse cover becomes
lost or damaged, the plug must not be used until a replacement, available from the
manufacturer, is obtained. It is important that the colour of the replacement fuse cover
corresponds with the colour marking on the base of the plug.
If the plug needs to be changed because it is not suitable for your socket, or becomes damaged,
it should be cut off and an appropriate plug fitted following the wiring instructions below. The
plug must then be disposed of safely, as insertion into a 13A socket is likely to cause an
electrical hazard.
IMPORTANT
The wires in the mains plug should be connected
as shown in the diagram.
The colours of the wires in the mains lead of the unit
may not correspond with the coloured markings
identifying the terminals in your plug. Connect them
as follows:The wire which is coloured blue must be connected
to the terminal which is marked with the letter 'N' or
coloured black.
The wire which is coloured brown must be
connected to the terminal which is marked with the
letter 'L' or coloured red.
There should be no connection to the earth terminal of your plug.
If a 13 Amp (BS 1363) Plug is used, a 3 Amp Fuse must be fitted, or if any other type of Plug
is used a 3 Amp or 5 Amp Fuse must be fitted, either in the Plug or Adaptor, or on the Distribution
Board.
