Grounding terminal for connecting inverter case.
200V class: single-phase 200~240V-50/60Hz
three-phase 200~230V-50/60Hz
400V class: three-phase 380~500V-50/60Hz
* Single – phase series don't have T/L3 terminal.
Connect to a (three-phase induction) motor.
Connect to braking resistors
Change parameters
This is a negative potential terminal in the internal DC main circuit. DC common power
can be input across the PA terminals (positive potential).
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.

Function
Shorting across F-CC causes for-
ward rotation; open causes slow-
down and stop.
Shorting across R-CC causes re-
verse rotation; open causes slow-
down and stop.
Shorting across RST-CC causes a
held reset when the inverter protector
function is operating. Note that when
the inverter is operating normally, it
will not operate even if there is a
short across RST-CC.
Shorting across S1-CC causes pre-
set speed operation.
Shorting across S2-CC causes pre-
set speed operation.
Shorting across S3-CC causes pre-
set speed operation.
