Hi, you have to reverse the mains polarity which is difficult with a grounded 3 prong AC plug, you can use a 3 to 2-pin adapter that will fit the electrical wall outlet both ways as in some countries the 2 pin sizes of wall outlets are not identical to impede reversing polarity. Another way is to cut the AC cord and replacing the fixed plug with a 3-pin grounded plug that can be opened and reverse the neutral and live wires inside the new plug, but make sure you don't mix your wiring with the ground wire usually green or green and yellow banded, always check the wiring afterwards with a multimeter if the ground (round pin) on both ends of the cord measure "continuous".
