*1: The T/L3 terminal is not provided for
single-phase models.
Use the R/L1 and S/L2 terminal as
input terminals.
*2: The inverter is supplied with the PO and
the PA/+ terminals shorted by means of
a shorting-bar.
Before installing the DC reactor (DCL),
remove the bar.
*3: When using the OUT output terminal in sink
logic mode, short the NO and CC terminals.
