• This unit has a handle mounted on top of the enclo-
sure for hand lifting only. Be sure unit is lifted and
transported safely and securely.
WARNING
HANDLE is not for mechanical lifting.
3.05 Input Power Connections
The Power Supply accepts input voltages from 208V to
460V. Input can be 50 or 60 Hz, single-phase or three-
phase. Depending on how the Power Supply was ordered
the Power Supply is factory wired for 230V single-phase
or 460V three-phase input. For any other input voltage,
the Power Supply must be internally reset.
NOTE
Refer to Section 3.06, Input Voltage Selection for
procedure.
A. Input Voltage Selection
The Power Supply is factory-wired for 230V single-phase
or 460V three-phase input depending on the order. For
any other input voltage, the Power Supply must be
changed using the procedure in Section 3.06.
B. Electrical Connections
The power source must conform to local and national elec-
tric codes. Recommended circuit protection and wiring
requirements are shown in Appendix I.
C. Opening Power Supply Enclosure
The left side panel of the Power Supply must be removed
to gain access to the input power connections and the
input voltage selection.
WARNING
Disconnect primary power at the source before as-
sembling or disassembling the Power Supply, torch
parts, or torch and leads assemblies.
1. Remove the five screws which secure the left side
panel (viewed from front of unit) to the frame assem-
bly.

Panel on the inside of the unit.
2. Carefully pull the Left Side Panel up and away from
the unit to gain access to the inside of the unit.
3.06 Input Voltage Selection
NOTE
For power supplies to use 575 VAC input power,
the unit must be setup for 460V three-phase op-
eration and the 575V Transformer Accessory must
be installed.
The Power Supply has three voltage settings; 208/230/
240VAC, 380/415VAC, or 460VAC. Power Supplies are
factory-wired for 230V single-phase or 460VAC three-
phase input depending on the order. Input voltage se-
lection is accomplished by switching an internal buss bar
and connector inside the Power Supply. Also, for single-
phase operation a jumper wire must be properly installed.
WARNING
Disconnect primary power at the source before as-
sembling or disassembling the power supply, torch
parts, or torch and leads assemblies.
To change the voltage selection use the following proce-
dure as required:
