Wiring Chapter 2-2
Ground Wiring
• Always use the ground terminal with the following ground resistance:
200-V Inverter: 100 W or less
400-V Inverter: separate ground,10 W or less
• Do not share the ground wire with other devices such as welding
machines or power tools.
• Always use a ground wire that complies with technical standards on
electrical equipment and minimize the length of the ground wire.
Leakage current flows through the Inverter. Therefore, if the distance
between the ground electrode and the ground terminal is too long, the
potential on the ground terminal of the Inverter will become unstable.
• When using more than one Inverter, be careful not to loop the ground
wire.
