WARNING

ELECTRIC SHOCK can kill.

Have an electrician install and service this equipment.

Turn the input power off at the fuse box before working on equipment.

Do not touch electrically hot parts.

The Multi-Source power supply should not be used if the green Safe Output light is not lit. The machine is designed to open its input contactor if output volt- age peaks exceed the limits set by certain approval agencies. If the Safe Output light is on, the output voltage is within it designed operating range.

-------------------------------------------------------------------

LOCATION

Place the power supply where clean cooling air can freely circulate in through the front louvers and out through the rear louvers. Dirt, dust or any foreign material that can be drawn into the welder should be kept at a minimum. Failure to observe these precau- tions can result in excessive operating temperatures and nuisance shut-downs.

STACKING

WARNING

FALLING EQUIPMENT can cause

injury.

• Two Multi-Source machines can be stacked.

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 Multi-Source on top of any other machine.

---------------------------------------------------------------------

Follow these guidelines when stacking:

1.Select a firm, level surface capable of supporting the total weight of up to two machines (1984 pounds/901kilograms).

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 on the second machine with the two pins on top at the front of the bottom machine.

Note: The machines must be stacked with the Case Front of each machine flush with each other.

INPUT AND GROUNDING

CONNETIONS

Note: A qualified electrician should connect the input power supply leads.

Input conductor is brought into the machine input box area through a hole in the rear panel sized to accom- modate 2" (trade size) conduit and fittings. This is more than adequate for the largest conductors required.

Conductors must be lugged to attach to the three 3/8" studs on the input reconnect panel and the 5/16"

ground stud marked with the symbol . The input voltage supplied determines the position required for the reconnect panel jumper. The three ranges on the standard machine are 380-415, 440-460 and 550-575. The machine is rated for 50 and 60 Hz operation. See the Input Connection Diagram located on the inside of Case Back Input Access Door.

The conductor and fuse sizes in the Technical Specification Section (A-1), are per the 1999 National Electrical Code. The sizes are in American Wire Gauge (and the next largest standard metric size in

mm2). National and local codes must be consulted before connecting a machine.

Protect the input circuit with the super lag fuses or delay type circuit breakers listed in the Technical Specification Section (A-1). (They are also called inverse time or thermal / magnetic circuit breakers.)

Use of fuses or circuit breakers with a lower amp rat- ing than recommended can result in nuisance tripping caused by inrush current even when machine is not being used for welding at high output currents.

Machines may be paralleled for increased output. The S20428 Paralleling Kit permits paralleling of two Multi-Source power supplies for supplying currents of up to 1000 amps, 100% duty cycle.
