Terminal name
Connect to the AC power supply. Do not connect these terminals to the
AC power supply when using the harmonic suppression unit HS900A
series.
Connect to the 3-phase motor.
Remove the short bar between PD and P terminals, and connect the
optional reactor DCL for improving power factor.
Connect the optional external braking resistor. For models equipped with
the braking resistor circuit, see "Chapter 20 Specifications". Models not
equipped with the braking resistor circuit does not have the RB terminal.
Connect the optional regenerative braking unit BRD, regenerative
converter RC700, and harmonic suppression unit HS900A.
The earth terminal for the Inverter case. Please connect this terminal to
the ground.
Conduct class-D ground work for 200V class, and class-C ground work
for 400V class.
Wire Connection and Optional Devices
* The RB terminal is mounted only on models
equipped with the drive circuit for braking
resistor.

Short circuit between P and PD
When shipped from the factory, P and PD
are short-circuited. If P and PD are not
connected, power is not supplied to the
main circuit, which disables operation.
