3.03 Electrical Input Requirements
NOTE
The Excel Arc ® 6045 comes equipped from the factory with a pre-connected three-conductor with earth
ground power cable that is connected at the welding power source for three phase electrical input power.
For direct wiring installation have a qualifi ed person install according to all applicable codes and instructions.
Operate the welding power source from a three-phase 60 Hz, AC power supply. The input voltage must match one of
the electrical input voltages shown on the input data label on the unit nameplate. Contact the local electric utility for
information about the type of electrical service available, how proper connections should be made, and any inspection
required.
The line disconnect switch provides a safe and convenient means to completely remove all electrical power from the
welding power supply whenever necessary to inspect or service the unit.
Do not connect an input conductor to the ground terminal.
Do not connect the ground conductor to an input line terminal.
Refer to "Figure 3-1: Electrical Input Connections" and:
1. Connect end of ground conductor to a suitable ground. Use a grounding method that complies with all applicable
electrical codes.
2. Connect ends of line 1 and line 2 and line 3 input conductors to a de-energized line disconnect switch.
3. Use "Figure 3-1: Electrical Input Connections" and "Table 3-3: Recommended Wire and Fuse Size" on page 3-3
as a guide to select line fuses for the disconnect switch. "Table 3-3: Recommended Wire and Fuse Size" provides
minimal information for selection of line conductors, fuses, and the equipment grounding conductor. This informa-
tion is from AS1966-1, AS/NZS 3652-(EMC Directive EN50199), EN60974-1 and AS60974.1.
