DANGER: HIGH VOLTAGE.
To avoid electrical shock, make sure to
disconnect the power supply 1 minute or more
before servicing the electrical parts. Even after
1 minute, always measure the voltage at the
terminals of main circuit capacitors or electrical
parts and, before touching , make sure that
those voltages are 50VDC or less.
