INSTALLATION PROCEDURES 3-2 Manual 0-2865
3.05 Input Power Cable Connections
WARNING
Disconnect primary power at the source before con-
necting the primary power cable to the power sup-
ply.
The primary input power cable (see CAUTION) is sup-
plied and must be connected by the user to the primary
power source. Power Supply is factory wired for 380-
415 VAV, three-phase power.
CAUTION
The primary input power cable must not be modi-
fied in any way as shielding is installed on the cable.
The power source must conform to local and national elec-
tric codes. Recommended circuit protection and wiring
requirements are shown in Appendix 1.
Connect the primary input power cable to the customer
power source per the following procedure:
1. At the free end of the input power cable, cut back
the insulation on the individual wires approxi-
mately 1/8 - 3/16 inch (3 - 5 mm).
2. Connect the ends of the individual wires to a cus-
tomer supplied plug per the following:
NOTE
All the input cable wires must be connected for
three-phase operation.
• Blue wire to Line 2 (Live)
• Black wire to Line 3 (Live), refer to Note
above
• Brown wire to Line 1 (Live)
• Green/Yellow wire to Ground (Power
Ground)
• Input Cable Shield Connector to Ground
(Power Ground)
NOTE
Refer to subsection 3.08 for procedures on install-
ing an earth ground for the power supply and work
cable.
3.06 Gas Connections
The Power Supply provides the liquid cooling and gases
to support operation of the Torch.
NOTE
Refer to the Torch Instruction Manual for infor-
mation on plasma and secondary gas selection and
requirements.
The following are available gases that can be used with
this System:
• Plasma Gases
Compressed Air, Nitrogen, Argon/Hydrogen
• Secondary Gases
Compressed Air, Carbon Dioxide (CO2), Nitrogen
Gas requirements vary depending on the application. The
gases are connected to the rear panel connections of the
power supply. Depending on the options installed and
the source of the gases will determine the installation of
connections, filters and regulators.
This sub-section includes information for connecting the
gas supplies to the Power Supply. The information is
grouped in paragraphs for different types of gases and
options per the following:
A. Using Shop Air Only
B. Using Plasma Shop Air and Secondary High
Pressure Gas Cylinder
C. Using High Pressure Gas Cylinders Only
A. Using Shop Air Only
Each Air Line Regulator on the rear of the power supply
has a built-in Air Line Filter. Filtering is required when
using an air compressor to insure that moisture and de-
bris from the supply hose does not enter the torch.
CAUTION
When using shop air, the air supply must be free of
oil, moisture, and other contaminants. Excessive
oil and moisture may cause double-arcing, rapid
tip wear, or even complete torch failure. Contami-
nants may cause poor cutting performance and
rapid electrode wear.
The following procedure is the recommended shop air
connection method:
1. Remove the factory installed plug fitting from the end
of the Fitting in the input port (IN) of the Two Stage
Air Line Filter Assembly.
2. Locate the 1/4 NPT to #4 (6 mm) barbed hose fitting
shipped inside the Torch Spare Parts Kit.
3. Install the barbed fitting into the input port (IN) of
the Two Stage Air Filter.
