The circuits is defined by HOP and COLD indications in the schematic diagram. Take the precautions below.
This schematic diagram is the latest at the time of model production start and subject to change without notice.
n
Precautions
NEVER touch the HOT part or the HOT and COLD parts at the same time, or you may get an electric shock.
NEVER short-circuit the HOL and COLD circuits, or the fuse may blow and the parts may break.
NEVER connect an instrument such oscilloscope to the HOT and COLD circuit simultaneously, or the fuse may blow.
Connect the ground of instruments to the ground of the circuit being measured.
MAKE SURE to unplug the power cord from the power outlet before removing the chassis.
When ordering parts, please check the part number of the parts list.
