Name
Main circuit power supply input (Use R/L1 and S/L2 for single-phase power supply inverter.
Do not use T/L3 of the models less than 0.75kW for other usage, such as a junction terminal.)
For inverter output
Remove the short bar between +2 and +1 when connecting DC reactor (option)
For power supply input (+1: positive electrode; – : negative electrode)*
For grounding (grounding should conform to the local grounding code.)
