Terminal function
Grounding terminal for connecting inverter.
There are 4 terminals in total. (1 terminal on upper side, 3 terminals on down side)
R/L1,S/L2,T/L3
240V class: three-phase 200 to 240V-50/60Hz
single-phase 200 to 240V-50/60Hz
120V class: single-phase 100 to 120V-50/60Hz
* Single-phase input: R/L1 and S/L2/N terminals
U/T1,V/T2,W/T3
Connect to a (three-phase induction) motor.
PC/-
This is a negative potential terminal in the internal DC main circuit. DC common power
can be input across the PA terminals (positive potential).
DC common power can not connect to 1-phase 120V models.
PO, PA/+
Terminals for connecting a DC reactor (DCL: optional external device). Shorted by a
short bar when shipped from the factory. Before installing DCL, remove the shorting-
bar. 1-phase 120V models cannot be used with DC reactors.
The arrangements of power circuit terminals are different from each range.
Refer to section 1.3.3.1) for details.
2.3.2
Control circuit terminals
The control circuit terminal board is common to all equipment.
Regarding to the function and specification of each terminal, please refer to the following table.
Refer to section 1.3.3.3) about the arrangement of control circuit terminals.

is always ON)
3 different functions can be assigned.
S1 Input
Shorting across S1-CC causes
preset speed operation.
2 different functions can be assigned.
