Refer to Figure 3-1:
1. Connect end of ground (GREEN or GREEN/YELLOW) conductor to a suitable ground. Use a grounding
method that complies with all applicable electrical codes.
2. Connect ends of line 1 (BLUE) and line 2 (BROWN) input conductors to a de-energized line disconnect
switch.
3. Use Table 3-1 as a guide to select line fuses for the disconnect switch.
Input Voltage Fuse Size
230V 40 Amps
Table 3-1: Electrical Connections
Fuse size is based on not more than 200 percent of the rated input amperage of the welding power source
(Based on Article 630, National Electrical Code).

Input Power
Each unit incorporates an INRUSH circuit. When the MAIN CIRCUIT SWITCH is turned on, the inrush circuit
provides pre-charging for the input capacitors. A relay in the Power Control Assembly (PCA) will turn on after
the input capacitors have charged to operating voltage (after approximately 5 seconds)
NOTE
Damage to the PCA could occur if 265 VAC or higher is applied to the Primary Power Cable.
