*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.
*4: 1ph-240V models have noise filter inside.
*5: 1ph-120V models cannot be used with
DC reactors.
*6: When external potentiometer is
connected by using P5 terminal,
set the parameter  = .
