supply
*1: The T/L3 terminal is not provided for
single-phase models.
Use the R/L1 and S/L2/N terminals 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: When VIA or VIB terminal is used as
logic input terminal, refer to section
7.2.1.
*5: To supply control power from an
external power supply for backing up the
control power supplied from the inverter,
an optional control power backup device
(CPS002Z) is required. In such a case,
the backup device is used at the same
time with the internal power supply of
the inverter.
The optional control power backup unit
can be used with both 240V and 500V
models.
*6: Set the slide switch SW1 to SINK side.
Default setting is PLC side.
*7: When STO terminal is used as
compliance with safety standards, refer
to Safety function manual (E6581860).
