Precautions on Grounding
• Be sure to turn OFF the main switch of the switchboard before perform-
ing the grounding work.
• If the welding source is used with rated input voltage: 480 V(6N0), the
ground resistance must be 100
by authorized or certified personnel.
1. Be sure to perform secure grounding work (ground resistance must be 100
on the welding source so as not to charge its case or lead to unstable operation.
2. Connect a grounding cable of 14 mm
"EARTH".
3. Be sure to ground the base metal (ground resistance must be 100
