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.

Check that input power is turned off with the disconnect switch connected to the welding power source.

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.
