A-2 INSTALLATION
IDEALARC® DC-1000
A-2
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 interference when stacking.
STACKING
Two DC-1000’s may be stacked by observing the following
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 connected for
the highest voltage. To change the connection, see the connec-
tion 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 L1, L2 and L3 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 located inside the machine near the input panel is
provided for this purpose. See the U.S. National Electrical Code
for details on proper grounding methods. (See Technical
Specifications)
SAFETY PRECAUTIONS
Read this entire installation section before you
start installation.
ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this installation.
• Turn the input power OFF at the
d i s c o n n e c t s w i t c h o r f u s e b o x
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.
-----------------------------------------------------------------------
FALLING EQUIPMENT can cause
injury.
• Do not lift this machine using lift bale if
it is equipped with a heavy accessory
such as trailer or gas cylinder.
• 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.

WARNING
LOCATION
Even though the machine is designed to operate
under a wide variety of environmental conditions, for
maximum reliability and long life the machine should
be located in a clean, dry place where there is free cir-
culation 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 possi-
bilities 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 operation,
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.
