Braking resistor [Note]

Note) This inverter have DC reactor included, and have advantage of reducing input current, reducing harmonics and power factor improvement. So, no DC reactor option is available. In case of requirement of additional reduction of harmonics or more power factor improvement, input AC reactor is recommended.

Q Main circuit

Terminal symbol	Terminal function
, PE	Grounding terminal for inverter casing
R/L1, S/L2, T/L3	Power input terminal
	0.75~110kW Three-phase 380~480V-50/60Hz
U/T1, V/T2, W/T3	Connect to a (3-phase induction) motor.
PA/+, PB	Connect a braking resistor.
	Change the parameters Pb, Pbr and PbCP if necessary.
	This is a negative potential terminal in the internal DC main circuit. DC power supply can be input
PC/-	across the PA/+ terminals (positive potential). (For 400V-30kW or more models, an optional circuit
	is needed to suppress a rush current.)
PO	Do not use.
