POWER INPUT CONNECTION

Connect terminal marked to earth ground per any existing local or national electrical codes.

Single Phase Input

Connect the supply lines to the upper and lower termi- nals of the line switch. Torque to 27.5in.-lbs.(3.0 Nm). Do not use center terminal of the line switch.

Three Phase Input

Connect the supply lines to the line switch. Torque to 27.5in.-lbs.(3.0 Nm).

Install in accordance with all local and national electric codes.

The V300-PRO is supplied with one cord connector to provide strain relief for the input power cord. It is designed for a cord diameter of .310-1.070” (7.9 - 27.2mm). The jacketed portion of the cord must go through the connector before tightening the connector screws.

CONNECTION OF WIRE FEEDERS TO THE INVERTEC

LN-25 Connection Instructions

1.Turn the Invertec power switch “off”.

2.Connect the electrode cable to the output terminal of polarity required by electrode. Connect the work lead to the other terminal.

3.LN-25 with remote control options K431 and K432. Use K876 adapter with K432 cable or modify K432 cable with K867 universal adapter plug. See con- nection diagram S19899 and S19309 or S19405 in Operator’s Mamual.

4.Place the local-remote switch in the “remote” posi- tion if output control is desired at the wire feeder rather than the Invertec. (LN-25 must have K431 and K432 options for remote output control opera- tion).

LN-7 Connection Instructions (not applicable to IEC machines with only 42V Aux.).

1.Turn the Invertec power switch “off”.

2.Connect the K480 or K1818-10 control cable from the LN-7 to the Invertec control cable connector. The control cable connector is located at the rear of the Invertec.

3.Connect the electrode cable to the output terminal of polarity required by electrode. Connect the work lead to the other terminal.

4.Place the local-remote switch in the “local” position to allow output control at the Invertec. (K864 remote control adapter and K857 remote control are required for remote output control. See con- nection diagram S19901.

5.Set the meter polarity switch on the rear of the Invertec to coincide with wire feeder polarity used. The wire feeder will now display the welding volt- age.

6.If a K480 or K1818-10 is not available, see con- nection diagram S19404 for modification of K291 or K404 LN-7 input cable with K867 universal adapter plug..
