Changing the Power Supply Voltage 230/115 V AC
To change the input mains voltage from 230 VAC to 115 VAC (or vice
versa) proceed as follows:
1. Loosen the four screws on the front and lift out the display (see also
page 25 ).
2. Note down the color and position of the wires in the terminal blocks,
and then loosen the terminal screws.
3. Unscrew the two screws that hold the metal cover and then remove it.
4. Unscrew the four screws that hold the mother PCB (the printed circuit
board with all the electrical components).
5. Remove the mother PCB and look at the back side. This is what you
should see (230 V AC configuration):
6. Unsolder and remove the jumper indicated by the arrow.
