Connect electric power to the cutting system
Connect the main power cord to the plasma power supply. Make sure that the line-disconnect switch is in
the OFF position. Use the applicable color codes for the main power cord wires.
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.
You must supply the main power cord for your cutting system. Select one that complies with local codes
and all regulations and input power requirements. Refer to General input power requirements on page
44.
The distance of the receptacle from the main box also can have an effect on size requirements for the main
power cord. For information about the codes in your location and the requirements for your site, speak with
a licensed electrician.
