The PS 4379 may be connected to the mains power outlet to
which other audio equipment is connected. The outlet should
have a clean earth. Avoid using mains power outlets, which
also power dimmer controlled lighting equipment.
Before connecting the unit to its AC power source, check if
the mains voltage of the unit (100 V - 240 V) is in accor-
dance with your local mains voltage.
IMPORTANT
The wires in this mains lead are colour coded in accordance
with the following code:

As the colours of the wires in the mains lead may not corres-
pond with the coloured markings identifying the terminals in
your plug, proceed as follows:
- The wire that is coloured green-and-yellow must be
connected to the terminal in the plug, which is
marked with the letter "E", or by the ground symbol,
or is coloured green.
- The wire that is coloured blue must be connected to
the terminal that is marked with the letter "N" or
coloured black.
- The wire that is coloured brown must be connected
to the terminal that is marked with the letter "L" or
coloured red.

will have an integral moulded 3-pin connector, which is provi-
ded to satisfy required local standards.
