Pilot light indicates when the supply lines to the welder are electrically "hot". This means that the welder input power and control transformers are ener- gized when the pilot light is on.

Input Circuit Plan: The AC-1500 is not intended for the connection of flexible supply cables. Instead, the following table may be used for planning of supply cables routed in conduit (See Technical Specifications in the Installation Section).

Starting Device: The pushbuttons located on the front panel are not connected to any kind of starting or stopping device. They are not necessary to operating the welder. If pushbutton operation is desired, an input contactor must be professionally installed and wired to the pushbutton assembly. The AC-1500 does not have an input contactor. Therefore, include an exter- nal starter or disconnect switch when planning the input circuit. Once the input circuit is energized, the pilot light on the front panel should glow. High voltage is present inside the machine. Do not open the machine enclosure.

Input Panel is made accessible by removal of the right side panel assembly (as viewed from front). Supply lines and grounding lead should be brought into the welder through the hole provided in the case rear panel. Connections to the input panel should be made as instructed on the wiring diagram attached to the welder. The grounding lead connection is to be made to the grounding stud provided on the welder base directly below the input panel.

Location of installation should be such that the welder cooling air exhaust area (the case rear panel) is free of any obstructions that could impede air flow. A dry location should be chosen. The welder should not be placed on a surface that is inclined enough that it creates a risk of the machine falling over

Control Circuit connections for wire feeder equip- ment are to be made per instructions on the wire feed- er diagram to the terminal strip provided under the hinged cover on the case front panel of the welding power supply. A strain relief strap to the right of the terminal strip is provided for attaching either the feed- er control and remote current control cables or both simultaneously. A grounding screw located just to the right of the terminal strip is provided for connecting the wire feeder grounding lead. All connections must be made with the welding power supply turned off.

Hand Welding with stick electrode or semiautomatic arc welding is not recommended since OCV exceeds the 80 volts RMS limit allowed by standards for such use. (Unit is within 100 volt allowable limit for auto- matic or mechanically guided welding.)

Scott Connection information for tandem arc applica- tion and paralleling of Scott connected units for tan- dem arc application is available. (See list of wiring diagrams.)

Isolated Auxiliary Power of 1000 volt.-amp., 115 volts AC is available at terminals #31 and #32 on the terminal strip under the hinged cover on the case front panel of the welder. The circuit is fused with an 8 amp slow blow fuse located in the nameplated section of the welder front panel.
