SAFETY PRECAUTIONS
Read this entire installation section before you
start installation.
WARNING
ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this installation.
• Turn the input power OFF at the
disconnect switch or fuse box
before working on this equipment.
Turn off the input power to any
other equipment connected to the
welding system at the disconnect
switch or fuse box before working
on the equipment.
• Do not touch electrically hot parts.
• Always connect the Power Wave grounding lug
(located inside the reconnect input access door)
to a proper safety (Earth) ground.
-----------------------------------------------------------------------
LOCATION
Even though the machine is designed to operate under
a wide variety of environmental conditions, for maxi-
mum reliability and long life the machine should be
located in a clean, dry place where there is free circu-
lation of clean air in through the front and out the back
of the machine. Dirt and dust that can be drawn into
the machine should be kept to a minimum. Failure to
observe these precautions can result in excessive
operating temperatures and nuisance shutdown of the
machine.
The case front incorporates a recessed control panel
which protects the controls and minimizes the possibil-
ities of accidental contact. This cover panel can be
flipped open to permit access to the enclosed control
section.
The individual case sides are removable for easy
access for internal service or inspection.
The case rear is equipped with a removable cover
plate, permitting easy access to the input panel.
The total enclosure, designed to permit outdoor opera-
tion, resists dust, salt, rain, humidity, and high and low
temperature extremes.
The machine uses a 38" (965mm) long base. The low
profile case facilitates installation of the machine under
a workbench and stacking the machines two high to
conserve floor space.
INSTALLATION
A permanent lifting eye is located at the top of the
machine and is positioned so that it acts as nearly as
possible through the center of gravity. This lift eye fits
under the case of the second machine without interfer-
ence when stacking.
STACKING
• Lift only with equipment of adequate lifting capacity.
• Be sure machine is stable when lifting.
• Do not stack more than two high.
• Do not stack the DC-1000 on top of any other
machine.
----------------------------------------------------------------------
Two DC-1000ʼs may be stacked by observing the fol-
lowing safety precautions:
1. Make sure the first or bottom unit is setting on a
level, well-supported surface.
2. The units must be stacked with their fronts flush,
making sure the two holes in the base rails of the
top unit are over the two pins located on top of the
bottom unit.
INPUT WIRING
Be sure the voltage, phase and frequency of the input
power is as specified on the welder nameplate.
Dual voltage (e.g. 230/460) models are shipped con-
nected for the highest voltage. To change the connec-
tion, see the connection diagram pasted to the inside
of the access panel in the case back.
Have a qualified electrician remove the rear access
panel and connect 3 phase AC power to terminals L 1 ,
L 2 and L 3 of the input panel in accordance with the
U.S. National Electrical Code, all local codes and the
Wiring Diagram located inside the machine.
The welder frame must be grounded. A stud marked
with the symbol
the input panel is provided for this purpose. See the
U.S. National Electrical Code for details on proper
grounding methods. (See Technical Specifications)
