Terminal symbol Terminal function
Grounding terminal for connecting inverter. There are 3 terminals in total. 2 terminals in
the terminal board, 1 terminal in the cooling fin.
R/L1,S/L2,T/L3
200V class: single-phase 200~240V-50/60Hz
three-phase 200~240V-50/60Hz
400V class: three-phase 380~500V-50/60Hz
* Single-phase input: R/L1 and S/L2 terminals
U/T1,V/T2,W/T3
Connect to a (three-phase induction) motor.
PA/+，PB
Connect to braking resistors.
Change parameters H, H, H, H if necessary.
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).
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.
