Ground Wiring
•
Always use the ground terminal of the 200-V Inverter with a ground resistance of 100
Ω
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 equip-
ment 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 termi-
nal of the Inverter will become unstable.
•
When using more than one Inverter, be careful not to loop the ground wire.
