2.5 Wiring overview

3-phase 200 V AC
3-phase 400 V AC
To wire the control circuit power
supply and main circuit power
supply separately, be sure to
remove the J51 connector
wire first.
Frequency setting unit

Purpose
Connect the input power supply
Three phase motor connection
Remove the short-circuit bar between terminals "PD/+1" and "P/+", and connect the optional power
factor improvement DC reactor.
Connect optional external braking resistors. (The RB terminal is provided for the inverters with
22KW or lower capacity.)
Connect optional regenerative braking units.
Inverter case ground terminal. Connect this terminal to the ground.
