Lead in the signal wires from jigs through this wire port.
(See the below note for details.)

Note
When leading in the wires through the grommet
Observe the following instructions.
• Route the wires not to touch to any other parts or board
inside the welding power source.
• Bind the binding band holder and the grommet with the
attached binding band.
When touching a printed circuit board, observe the following item to prevent elec
-
trostatic destruction of the printed circuit board.
Before starting an operation, for example, touch any metal part of the case with your hand to discharge static
electricity
Note
Keep the signal lines from a jig and/or a robot away from the
welding arc area, the welding torch, the base-material-side
cable, etc. to prevent troubles caused by incorporation of the
high frequency wave.
Keep the wiring length within 10 m.
