hi rajesh,
If you have an AC model, you can plug it into any 220-240 volt outlet pretty much,
BUT make sure it can support about 16 amps, you'll blow your fuses out in no time :)
If you have the DC one, you need a 220AC-48DC converter, be careful with those also, because you'll fry your own fingers if you touch the poles (trust me, done it too many times:).
cheers!
