SECTION 3:
INSTALLATION
PROCEDURES
3.01 Introduction
NOTE
Depending on how the system was ordered, some
Power Supply options may already be installed.
If option(s) have been factory installed some of the
instructions may not apply. It is recommended
that all sub-sections be read for general informa-
tion.
This section describes installation of the Power Supply
and connecting the Torch.
These instructions apply to the Power Supply only; in-
stallation procedures for the Torch, Options, and Acces-
sories are given in Manuals specifically provided for those
units.
The complete installation consists of:
1. Site selection
2. Unpacking
3. Connections to Power Supply
a. Input power
b. Work cable
c. Gas connections
d. Torch Installation
e. Connecting auxiliary devices
4. Grounding
5. Operator training
3.02 Site Selection
Select a clean, dry location with good ventilation and ad-
equate working space around all components.
NOTE
Review Important Safety Precautions (page 1) to
be sure that the selected location meets all safety
requirements.
The power supply is fan cooled by air flow through the
front panel to the rear panel. Air flow must not be ob-
structed. Provide at least 2 feet (0.61 m) in the rear and at
least 6 inches (0.15 m) on each side for clearance . Pro-
vide sufficient clearance in front of the unit to allow ac-
cess to the front panel controls (minimum 6 inches or 0.15
m).
CAUTION
Operation without proper air flow will inhibit
proper cooling and reduce duty cycle.
Review the safety precautions in the front of this manual
to be sure that the location meets all safety requirements.
3.03 Unpacking
NOTE
Equipment that was ordered as a system is pack-
aged in one shipping carton. All options and the
torch are factory installed.
Each component of the system is packaged and protected
with a carton and packing material to prevent damage
during shipping.
1. Unpack each item and remove all packing material.
2. Locate the packing list(s) and use the list to identify
and account for each item.
3. Inspect each item for possible shipping damage. If
damage is evident, contact your distributor and/or
shipping company before proceeding with system
installation.
3.04 Input Power Cable Connections
The Power Supply is factory wired to accept input volt-
ages of 380-415 VAC, 50 or 60 Hz, three-phase power.
A. Power Source
The power source must conform to local and national elec-
tric codes. For suggested circuit protection and wiring
requirements refer to Appendix I.
WARNING
Disconnect primary power at the source before as-
sembling or disassembling the Power Supply, torch
parts, or torch and leads assemblies.
B. Input Power Cable Connections
The shielded input power cable must be connected to a
380-415 VAC, three-phase power source. Refer to the fol-
lowing procedure:
