4.6 Wiring of Voltage Detection Cable at Base Metal Side
When the extension cable is 30 m or more in length in total, use of the voltage detection cable at the base metal side is
recommended.
The voltage detection cable needs to be wired so that the correct feedback of the arc voltage can be obtained. Connect the
voltage detection cable as near as possible to the base metal to avoid detection of voltage decrease.
Use the voltage detection cable at base metal (optionally available: K5416N00 or K5416G00) by connecting with the wire
feeder or to the voltage direct detection terminal at the base metal side on the front of welding power source.
When using the voltage detection cable, set the internal function F38 to "1". ( 6.7.1

4.6.1 Wiring to welding power source
This section explains how to connect the voltage detection cable at the base metal side to the voltage direct detection
terminal at the base metal side of the welding power source.
1.
Check that input power is turned off with the disconnect switch connected to the welding power source.
2.
Connect the voltage detection cable at the base metal side to the voltage direct detection terminal at the base
metal side.
Wiring of voltage detection cable is complete.
•
Ensure to start the operation only after shutting off the input power by the contactor of
the power distribution box connecting the welding power source. Otherwise, electric
shock may occur.
