WARNING
ELECTRIC SHOCK CAN KILL
The plasma power supply contains dangerous electric voltages that
can seriously injure or kill you. Even if the plasma power supply is
turned OFF, you can still get a serious electric shock if the plasma
power supply remains connected to an electric power source.
Use extreme caution if you do diagnosis or maintenance tasks when
the plasma power supply remains connected to an electric power
source and the outer cover or panels are removed. All work that
requires removal of the plasma power supply outer cover or panels
must be done by a qualified technician. Refer to the Safety and
Compliance Manual (80669C) for more safety information.
