From (a)
*1: The inverter is shipped with the terminals PO and PA/+ shorted with a bar (200V-45kW or smaller, 400V-75kW or smaller).
Remove this shorting bar when installing a DC reactor (DCL).
For 200 V - 55 kW or more, and 400 V - 90 kW or more models, be sure to install the DC reactor.
*2: The DC reactor is built in for models 200V-11kW~45kW and 400V-18.5kW~75kW.
*3: The noise filter is built in for models 200V-45kW or smaller and all of 400V.
*4: External braking resistor (option). Dynamic braking drive circuit built-in (GTR7) as standard for models 160kW or smaller.
*5: Power generation braking Unit (option). When the external braking resistor (optional) is used on 200 kW or more models, the separate power braking unit (optional) is required.
*6: To supply a DC power, connect the cables to the PA/+ and PA/- terminals.
*7: If you want to use a DC power supply to operate the inverter (200V: 18.5kW or more, 400V: 22kW or more), be sure to contact your supplier customer support center, because an
inrush current limiting circuit is required in such a case.
*8: For models 200V-75kW and 400V-110kW or larger, three-phase power input is necessary to drive the fan if you want to use a DC power supply.
*9: The functions assigned to terminals OUT1, VI/VII and RR/S4 can be switched by changing parameter settings.
*10: 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.
*11: The optional control power backup unit can be used with both 200V and 400V models.

Connect to a (3-phase induction) motor.
Connect a braking resistor. (For the optional dynamic braking unit, connect it between PA/+ and PC/-.)
Change the parameters , and if necessary.
200kW models and smaller are not equipped with terminal PB. If your are using such a model and you wish to use a braking resistor, you will need
to purchase a braking unit separately.
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 (200V: 45kW or
smaller, 400V: 75kW or smaller). Before installing DCL, remove the short bar.
200V class: 75kW
400V class:110kW~500kW

Shorting across F-CC causes forward rotation; open causes deceleration stop.
(Across ST-CC is short state.)
Shorting across R-CC causes reverse rotation; open causes deceleration stop.
(Across ST-CC is short state.)
The motor is on standby if ST and CC are connected. It coasts to a stop if this connection
is broken. This terminal can be used for interlocking.
Shorting and then opening RES-CC cancels the status held by an inverter protective
function. When the inverter is operating normally, shorting and then opening RES-CC
produces no effect.
Shorting across S1-CC causes preset speed operation.
Shorting across S2-CC causes preset speed operation.
Shorting across S3-CC causes preset speed operation.
SW3: When SW4 is in the S4 position, S4 and CC are shorted and preset speed operation
is selected.
