INPUT POWER, GROUNDING AND CONNECTION DIAGRAMS
WARNING
ELECTRIC SHOCK can kill.
•Do not touch electrically live parts such as output terminals or internal wiring.
•All input power must be electrically discon- nected before proceeding.
1.Before starting the installation, check with the local power company if there is any question about whether your power supply is adequate for the voltage, amperes, phase, and frequency spec- ified on the welder nameplate. Also be sure the planned installation will meet the U.S. National Electrical Code and local code requirements. This welder may be operated from a single phase line or from one phase of a two or three phase line.
2.Models that have multiple input voltages specified on the nameplate (e.g. 208/230) are shipped con- nected for the highest voltage. If the welder is to be operated on lower voltage, it must be recon- nected according to the instructions in Figure A.1 for dual voltage machines and Figure A.2 for triple voltage machines.

LOCATION
Locate the welder in a dry location where there is free circulation of clean air into the louvers in the back and out the front. A location that minimizes the amount of smoke and dirt drawn into the rear louvers reduces the chance of dirt accumulation that can block air pas- sages and cause overheating.
WARNING
Make certain that the input power is electrically disconnected before removing the screw on the reconnect panel access cover.
