This section explains the procedure for connection to the terminal for external connection.
1.
Check that input power is turned off with the disconnect switch connected to the welding power source.
2.
Remove the attaching screws and open the cover for external connection.
3.
Remove the blind bush and pass the cable through.
●
Process any given blind bush among the several available types.
4.
Connect the cable to the terminal for external connection.
●
Strip the cable cover by 25/64 to 7/16" (10 to 11 mm) from the end while pressing the button on the terminal block
and insert the cable.
●
Fix the cable with cable ties so that no gap may be created between the cable and the blind bush.
To prevent electric shock, ensure to follow the instructions below:
Wiring should be performed by qualified persons or persons familiar with the welding
machine.
Do not touch the input and output terminals and the internal live electrical parts of the
welding power source.
Before starting the work, make sure to cut the input power with the disconnect switch
connected to the welding power source and wait three minutes or more. In addition, do
not turn on the primary power until the work is complete.
Do not use damaged cable or cable without grounding.
Securely attach the case and cover of the welding power source after connecting the
cables.
Use the following cable for connecting to the terminal for external connection:
Cable thickness: AWG22 to AWG16 (0.33 to 1.3 mm
2
)
Using a cable or terminal not specified will be a cause of heat generation and fire.
Furthermore, cable other than specified cannot be connected to the terminal for
external connection.
CAUTION
The control cable drawn out from the terminal for external connection should be kept
away from the welding power cable or the torch cable as much as possible.
Otherwise, failure may occur due to noise during use.
Do not pull out the cables other than the cable that is connected with the terminal block
on the printed circuit board.
Malfunction or error may occur.
