Remove the power from the cutting system

It is necessary to remove the power from the cutting system for many procedures.

Warning

ELECTRIC SHOCK CAN KILL

If the line-disconnect switch is not in the OFF position you can get a serious electric shock. Electric shock can seriously injure or kill you.

The line-disconnect switch must be in the OFF position before you connect the power cord to the cutting system. It must REMAIN in the OFF position until all installation steps are complete. In the United States, use a "lock out/tag out" procedure until installation is complete. In other countries, follow the appropriate national and local safety procedures. Refer to the Safety and Compliance Manual (80669C) for more safety information.

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.

Warning

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. Refer to the Safety and Compliance Manual (80669C) for more safety information.

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 gives you easier access to the torch and consumable parts.

Set the line-disconnect switch to the OFF position.
If the cutting system is not hard wired, disconnect the main power from the electric power.

If the cutting system is hard wired, you cannot disconnect the main power from the electric power.

Even if you remove the power from the cutting system, you can still get a serious electric shock if the plasma power supply stays connected to an electric power source. Use extreme care during service and maintenance when the cutting system is connected to electricity.
Make sure that the power-indicator Light Emitting Diode (LED) is not illuminated on the plasma power supply and cooler if applicable, gas connect console, and torch connect console.
