Requirements for grounding
To make sure of personal safety and correct operation, and to decrease electromagnetic
interference (EMI), the plasma power supply must be correctly grounded.
 The plasma power supply must be grounded through the power cord according to
national and local electrical codes.
 1-phase service must be of the 3-wire type with a green or green/yellow wire for the
protective earth ground and must comply with national and local requirements. Do not use
a 2-wire service.
 3-phase service must be of the 4-wire type with a green or green/yellow wire for protective
earth ground and must comply with national and local requirements.
Refer to the Safety and Compliance Manual (80669C) for more information on grounding.
For mechanized cutting systems, refer to EMI grounding and shielding best practices in the
Powermax65/85/105 SYNC Mechanized Cutting Guide (810480).
Rated output (cutting power) of the plasma power supply
Wattage output shows a plasma power supply’s cutting power more than its amperage output. The
rated outputs for the systems are as follows:
To calculate the cutting power in watts (W), multiply the maximum output amperage (A) by the
maximum rated output voltage (VDC). For example:
65 A x 139 VDC = 9035 W (9.0 kW)
Voltage configurations
The plasma power supply automatically adjusts for correct operation at the current input voltage.
You do not have to change or rewire components. But you must do the following:
 Install the Hypertherm cartridge in the torch. Refer to Step 3 – Install the cartridge on
page 66.
 Make sure that the output current (A) is correct for the cartridge that you installed. If
necessary, turn the adjustment knob on the front panel to adjust the output current. Refer to
Step 6 – Adjust the output current (A) and operating mode if necessary on page 72.
To operate the plasma power supply at full output and at its rated duty cycle (refer to Prevent
overheating on page 83), you must make your electrical service the correct size. The following
tables show the maximum rated output for typical input voltages. The output setting that you use
relates to the thickness of the workpiece and the limit of the input power to the plasma power
supply.
