*1: The T/L3 terminal not providedfor signal-
phase models.
Use the R/L1 and S/L2 terminal as input
terminals.
*2: The inverter came with the P1 and the P(+)
terminals shorted by means of a shoeting
bar.
Before installing the DC reactor (DCL),
remove the bar.
*3: When using the DRV output terminal in sink
logic mode, short-circuit the OM and COM
terminals.
