SAFETY PRECAUTIONS

ELECTRIC SHOCK can kill
• Only qualified personnel should install this
machine.
• Turn the input power OFF at the disconnect
switch or fuse box before working on the
equipment.
• Do not touch electrically hot parts.
• Always connect the Idealarc DC-600 grounding
terminal to a good electrical earth ground.
• Set the Idealarc DC-600 Power ON/OFF PUSH
BUTTON to the OFF position when connecting
power cord to input power.

SELECT PROPER LOCATION

Place the Idealarc DC-600 where clean air can freely circulate in
through the front intake and out through the rear louvers. Dirt,
dust, or any foreign material that can be drawn into the machine
should be kept at a minimum. Not following these precautions can
result in the nuisance shutdown of the machine because of
excessive operating temperatures.
STACKING
Three IDEALARC DC-600 machines can be stacked.
DO NOT stack more than three machines in one grouping.
DO NOT stack the Idealarc DC-600 on another type of machine.
Following these guidelines when stacking:
1. Select a firm, level surface capable of supporting the total
weight of up to three machines 720kg.
2. Set the bottom machine in place.
3. Stack the second machine on top of it by aligning the two
holes in the base rails of the second machine with the two
pins on top front of the bottom machine.
4. Repeat process for third machine.
Note: The machines must be stacked with the Case Front of each
machine flush with each other. See Figure A.1.

TILTING
The Idealarc DC-600 must be placed on a stable, level surface so
it will not topple over.

ELECTRICAL INPUT CONNECTIONS

Before installing the machine, check that the input supply voltage,
phase, and frequency are the same as the machine's voltage,
phase, and frequency as specified on the machine's rating plate
on the Case Rear Panel Assembly. Input power supply entry is
through the hole in the Case Rear Panel Assembly. See Figure
A.2 for the location of the machine's input cable entry opening,
Input Contactor (CR1), and reconnect panel assembly for multi-
voltage machines.

FUSE AND WIRE SIZES

Protect the input circuit with the super lag fuses or delay type
circuit breakers. They are also called inverse time or thermal/
magnetic circuit breakers.
DO NOT use fuses or circuit breakers with too low amp rating.
This can result in "nuisance" tripping caused by inrush current
even when machine is not being used for welding at high output
currents. Use input and grounding wire sizes that meet local
electrical codes or see the Technical Specifications page in this
manual.

GROUND CONNECTION

Ground the frame of the machine. A ground terminal marked with
the symbol (
of the machine near the input contactor. Access to the Input Box
Assembly is at the upper rear of the machine. See your local and
national electrical codes for proper grounding methods.
