The cores in the mains lead are colored in accordance with the following
code:

Green and Yellow - Earth  Blue - Neutral

Brown - Live

As colors of the cores in the mains lead of this appliance may not corre-
spond with the colored markings identifying the terminals in your plug, pro-
ceed as follows:

•The core which is colored green and yellow must be connected to the

terminal in the plug marked with the letter E, or with the earth sym-
bol, or colored green, or green and yellow.

•The core which is colored blue must be connected to the terminal

marked N, or colored black.

personnel who should refer to the table below.The green/yellow wire shall
be connected directly to the unit’s chassis.

Warning: If the ground plug is defeated, certain fault conditions in the unit
or in the system to which it is connected can result in full line voltage
between chassis and earth ground. Severe injury or death can then result if
the chassis and earth ground are touched simultaneously.
