Avoid prolonged, unprotected contact between solder and your skin! When solder ing, do not inhale solder fumes or exposeeyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handlingfood.
� WARNINGComponents having special characteristics are marked and must bereplaced with parts having specification equal to those originally installed.
THE WIRES IN THIS MAINS LEAD ARE COLOURED INACCORDANCE WITH THE FOLLOWING CODE:
GREEN-AND-YELLOW : EARTHBLUE : NEUTRALBROWN : LIVE
As the colours of the wires in the mains lead of this apparatus maynot correspond with the coloured markings identifying the terminals inyour plug, proceed as follows:The wire which is coloured GREEN and YELLOW must beconnected to the terminal in the plug which is marked by the letter Eor by the safety earth symbol or coloured GREEN and YELLOW.The wire which is coloured BLUE must be connected to theterminal which is marked with the letter N or coloured BLACK.The wire which is coloured BROWN must be connected to the terminalwhich is marked with the letter L or coloured RED.
