You can get these chargers cheaper from Soanarplus

Same part number.

Do not disconnect the mains earth.
DO disconnect the output negative from the earth. From memory, on the sister unit (24 volt 6 amp) it's a single green/yellow wire from the pcb to the chassis.

I've got a number of these now. A 12 volt 6 amp unit for general charging. Several years old now and has a noisy fan. A 12 volt 12 amp unit fitted to a push along fork lift at work. And 2 x 24 volt 6 amps for charging my EVT at work.

Edit: The case is grounded because it's a metal case. It's a safety issue.
