Inverter output
Use main circuit power input.
(Use terminals R/L1 and S/L2 for single-phase
inverters. Never use terminal T/L3.)
Braking resistor connection
When connecting optional DC reactor, remove the
main circuit short-circuit bar between +2 and +1.
For grounding (according to the local grounding
code)
