Manual 0-2470 21 INSTALLATION
3.06 ELECTRICAL CONNECTIONS (continued)
Both input voltage settings on the power supply must correspond
to the actual primary input voltage.
Systems ordered for 230V operation come supplied with a 230V
single-phase input power cable attached. For any other input
voltage, the 230V input power cable must be removed and
replaced with an appropriate power cable.
Disconnect primary power at the source before disassembling
the power supply, torch, or torch leads.
Refer to Figure 3-F (page 22) and:
1. Remove the access panel on the rear panel of the unit and
disconnect the factory-installed 230V input power cable.
Loosen the strain relief and remove the cable.
Input power connections can be made directly to a properly
fused disconnect or by using a plug which conforms to the
recommended ratings.
The primary power source, power cable, and plug all must
conform to local electric code and the recommended circuit
protection and wiring requirements (see Table 3-A, page 22).
2. Before connecting the replacement input power cable, strip
back the outer covering approximately 3 inches (76 mm) to
expose the individual wires. Then cut back the insulation on
the individual wires approximately 1/8 - 3/16 inch (3-5 mm).
3. Install a #10 ring terminal on the ground (GND) wire of the
input power cable.
Make sure the ground wire is designated as GND on the other
end of the cable. Electric shock and damage to the unit could
occur if power is applied to the GND terminal.
4. Connect the input power cable according to Figure 3-F.
Terminal L3 is not used for single-phase connections.
