Connections
WARNING
Disconnect primary power at the source before as-
sembling or disassembling the Power Supply, torch
parts, or torch and leads assemblies.
The Power Supply operates on three phase, 380/415VAC,
± 10% 50/60Hz input.
CAUTION
The primary power source, power cable must all
conform to local electric code and the recommended
circuit protection and wiring requirements (refer
to table in Appendix I).
The Power Supply is supplied with a three-phase, four
conductor, input EMC power cable attached. Connect
the supplied input EMC power cable to the customer's
power source as follows:
NOTE
The input power cable must not be modified in any
way as filtering beads are installed on the cable.
1. Strip back the outer covering approximately 3
inches (76 mm) to expose the individual wires at
the free end of the cable.
2. Cut back the insulation on the individual wires
approximately 1/8 - 3/16 inch (3-5 mm).
