Note) This product has high voltage circuits inside, and the voltage will be kept for a while by big capacitors. So, before starting disassembly(especially removing the Buss Bars(CND3947)), make sure if the voltage of +VH and -VH become low enough after turning off the power supply(+B & ACC). If you want to discharge the capacitors faster, connect the resistors of same value in parallel with the original discharge resistors (R241 - R246).
