Changing the Power Supply Voltage 230/115 V AC
To change the input mains voltage from 230 V AC to 115 V AC (or vice versa)
proceed as follows:
1. Loosen the four screws on the front and lift out the display (see also page
23
).
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 expect to see for a 230 V AC configuration:

6. Unsolder and remove the jumper indicated by the arrow.
