Install a remote on-off switch
As an alternative to using the main power supply, do these steps to install your own remote on-off switch so that you can control power to the gas connect console, TorchConnect™ console, and other parts.

   | 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.
