Terminal Function
L, N
Single-phase AC input terminals which are generally connected with
the power supply.
R, S, T
Three-phase AC input terminals which are generally connected with
the power supply.
PB, (+) External dynamic braking resistor terminal
(+), (-) Input terminal for DC bus
U, V, W
Three-phase AC output terminals which are generally connected to
the motor.
PE Protective grounding terminal
Note:
 Do not use asymmetrically constructed motor cables. If there is a symmetrically constructed
grounding conductor in the motor cable in addition to the conductive shield, connect the
grounding conductor to the grounding terminal at the inverter and motor ends.
 Route the motor cable, input power cable and control cables separately.
