Terminal symbol Terminal function
Grounding terminal for connecting inverter. There are 3 terminals in cooling fin or
mounting part of EMC plate.
R/L1,S/L2,T/L3
240V class : Three-phase 200 to 240V-50/60Hz
: Single-phase 200 to 240V-50/60Hz
500V class : Three-phase 380 to 500V-50/60Hz
* Single-phase inputs are R/L1 and S/L2/N terminals.
U/T1,V/T2,W/T3
Connect to three-phase motor.
PA/+, PB

if necessary.
PA/+
This is a positive potential terminal in the internal DC main circuit.
DC common power can be input with PC/- terminal.
PC/-
This is a negative potential terminal in the internal DC main circuit.
DC common power can be input with PA/+ terminal.
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 short bar.
The arrangements of power circuit terminals are different from each range.
Refer to section 1.3.3.1) for details.
