Position the power supply
Locate the power supply near an appropriate power receptacle for your installation: 200 – 480 volts (CSA 1-phase),
200 – 600 volts (CSA 3-phase), or 380/400 volts (3-phase CE). The power supply has a 10-foot (3 m) power cord.
Allow at least 10 inches (0.25 m) of space around the power supply for proper ventilation.
The power supply is not suitable for use in rain or snow.
To avoid toppling, do not set the power supply on an incline greater than 10 degrees.
Prepare the electrical power
Hypertherm (designated HYP on the data plate) input current ratings are used to determine conductor sizes for power
connection and installation instructions. The HYP rating is determined under maximum normal operating conditions and
the higher HYP input current value should be used for installation purposes.
The maximum output voltage will vary based on your input voltage and the circuit’s amperage. Because the current draw
varies during startup, slow-blow fuses are recommended as shown in the charts below. Slow-blow fuses can withstand
currents up to 10 times the rated value for short periods of time.
Caution: Protect the circuit with appropriately sized time-delay (slow-blow) fuses and a
line-disconnect switch.
