INSTALLATION

D.Check all connections for proper tightness. En- sure all connections are correct and well insu- lated.

E.Figure 2-2 illustrates the input voltage terminal board and the input voltage link connections. The particular voltages from which this power source may be operated are stated on the rating plate. The voltage links were factory set for highest voltage stated on the rating plate. If the power source is to be operated on another stated input voltage, the links must be reset for that particular input voltage. Always verify the input voltage and check the link arrangement regardless of factory setting. The voltage links are set up by re-configuring the copper link bars to the silk screened voltage designations for the desired voltage.

2.4OUTPUT WELDING CONNECTIONS (SECONDARY)

Before making any connections to the power source output terminals, make sure that all primary input power to the machine is off.

The output terminals are located on the front panel (Figure 2.3). Two output terminals are provided. One NEGATIVE (-) terminal is located at the bottom right hand corner and the POSITIVE (+) terminal is located at the bottom left corner. The output cable connections will depend on the materials and welding process desired. Table 2-2 provides the recommended cable output sizes.

*Total cable length includes work and electrode cables. Cable size is based on direct current, insulated copper conductors, 100 percent duty cycle and a voltage drop of 4 or less volts. The welding cable insulator must have a voltage rating that is high enough to withstand the open circuit voltage of the machine.

2.5CONTROL CONNECTIONS Refer to Figure 2-3.

2.5.1 Remote Control (Optional)

This function is provided by an optional 14-pin recep- tacle (J2) located on the front panel directly below connector J1. It mates with a plug from any optional remote control device (see 1.4.2). This receptacle is operative only if the panel remote switches on the power source front panel are in the "Remote" position.

2.5.2 Auxiliary 115 V AC Receptacle (Option)

A 115 Vac receptacle is provided to supply power to accessories such as a water cooler, heated C02 regu- lator, or small hand tools. The receptacle is rated 115 Vac / 10 amps.

2.5.3 - 42V Circuit Breaker (CB1)

The 42V resettable circuit breaker (CB1) protects the 42 volt control circuitry against over current. (Table 52 provides troubleshooting information).

2.5.4 - 115V Circuit Breaker (CB2)

The 115V resettable circuit breaker (CB2) protects the 115 volt auxiliary receptacle and control circuitry against over current. (Table 5-2 provides troubleshooting infor- mation).
