6. Keep all panels securely in place.
7. All electrical conductors within 50 ft (15.2m) of the
	welder should be enclosed in grounded, rigid
	metallic conduit or equivalent shielding. Flexible
	metallic conduit is generally not suitable.
8. When the welder is enclosed in a metal building,
	several earth driven electrical grounds connected
	(as in 5b above) around the periphery of the build-
	ing are recommended.
Failure to observe these recommended installation
procedures can cause radio or TV interference prob-
lems.
INPUT CONNECTIONS
Be sure the voltage, phase, and frequency of the input
power is as specified on the rating plate, located on
the bottom of the machine.
		WARNING
		ELECTRIC SHOCK can kill.
		• Have a qualified electrician install
		and service this equipment.
		• Turn the input power OFF and unplug
		the machine from the receptacle
		before working on this equipment.
• Allow machine to sit for 5 minutes minimum to
allow the power capacitors to discharge before
working inside this equipment.
• Do not touch electrically hot parts.
• Machine must be plugged into a receptacle that
is grounded according to the National Electrical
Code and local codes.
• Do not remove or defeat the purpose of the
power cord ground pin.
