WARNING
ELECTRIC ShOCK can kill.
ONLY A QuALIFIED ELECTRICIAN ShOuLD CONNECT ThE INPuT LEADS TO ThE FX450. CONNEC-
TIONS ShOuLD bE MADE IN ACCORDANCE WITh ALL LOCAL AND NATIONAL ELECTRI- CAL CODES AND ThE CONNECTION DIAGRAM LOCATED ON ThE INSIDE OF ThE RECON- NECT/INPuT ACCESS DOOR OF ThE MAChINE. FAILuRE TO DO SO MAY RESuLT IN bODILY INJuRY OR DEATh.
INPuT FuSE AND SuPPLY WIRE CONSIDERATIONS
Refer to Specification in this Installation Section for recommended fuse, wire sizes and type of the copper wires. Fuse the input circuit with the recommended super lag fuse or delay type breakers (also called "inverse time" or "thermal/magnetic" circuit breakers). Choose input and grounding wire size according to local or national electrical codes. Using input wire sizes, fuses or circuit breakers smaller than recom- mended may result in "nuisance"
INPuT CONNECTION
(See Figure A.1)
Use a
To access the reconnect/input supply connection blocks, remove the 8 screws that secure the case top of the welder and remove the case top.
INPuT VOLTAGE SELECTION
Welders are shipped connected for 460 Volt input voltage. To move this connection to a different input voltage, see the diagram located on the inside panel in the reconnect/input connection area, also illustrat- ed below. If the Auxiliary lead (indicated as ‘A’) is placed in the wrong position and power is applied to the machine, the machine will protect itself and dis- play an error message:
•"Err" "058" will be shown on the display.
•The control board and switch boards will blink out error 58 on their status leds.
•The weld output will be turned off and the control board will force itself into an idle state.
•The machine will need to have the misconnect condition removed before it will recover.

RECONNECT TERMINAL BLOCK
POWER SUPPLY ACCESS HOLE
• Route input power cable through this hole.
RECONNECT TERMINAL BLOCK
•Reconnects auxiliary transformers for the proper input voltages
POWER SUPPLY TERMINAL BLOCK
•Line Cord/Cable attaches here.
•A ground terminal marked with the symbol shown
is provided separate from this block for connecting the ground lead of the line cord. (See your local and national electrical codes for proper grounding methods.)
