The G2 units are switch mode, but it has a primary filter electrolytic only rated for 200V. When you connect it to 240v, that capacitor sees about 320v, so generally after a short while it explodes and destroys the power supply.
Also, if you just replace the capacitor, it will be fine, and will operate OK on 240V, but only at 12A. I developed all-new firmware to replace the stock firmware that checks to see what voltage is coming in and allows you to program different amperages for L1/L2. Sadly, reprogramming firmware requires a special adapter, so even if I gave it away, it wouldn't be of much use.
