*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 in 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 NO output terminal in
source logic mode, short the P24 and
OUT 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
f109=3.
*7: When VI terminal is used as a contact
input terminal, refer to page B-12.
