Remove the power from the cutting system
Many procedures in this section require you to remove the power from the cutting system. To do this
safely, use the following procedure.

Before you remove the power from the cutting system, it can be helpful to
move the torch to the edge of the cutting table and raise the torch lifter to
its highest point. This provides easier access to the torch and consumable
parts.
1. Set the line-disconnect switch to the OFF position.
WARNING
ELECTRIC SHOCK CAN KILL
Disconnect electrical power before doing any maintenance.
The line-disconnect switch must remain in the OFF position until all
maintenance steps are complete.
In the United States, use a “lock out/tag out” procedure until
maintenance is complete. In other countries, follow the appropriate
national and local safety procedures.
See the Safety and Compliance Manual (80669C) for more safety
precautions.
The plasma power supply contains dangerous electric voltages that can
cause injury or death.
Even if the cutting system is turned OFF, you can still get a serious
electric shock if the cutting system remains connected to an electric
power source.
Use extreme caution if you do diagnosis or maintenance tasks when the
plasma power supply remains plugged in and the panels on the plasma
power supply are removed.
MACHINE MOTION CAN CAUSE INJURY
The end-use customer and the cutting machine supplier are responsible
for providing protection against the hazardous moving parts of this
cutting system.
Read and follow the instruction manual provided by the cutting machine
supplier.
See the Safety and Compliance Manual (80669C) for more safety
precautions.
