Terminal mark Terminal
Function
L1, L2
Single-phase power
supply input terminals
The terminals are used to connect to the
power supply. L1 is connected to the live
wire and L2 is connected to the neutral
wire.
R, S, T
Three-phase power
input terminals
Connected to the three-phase AC power
supply.
(+), BR Terminals for
connecting the braking
resistor
Used to connect the braking resistor.
U, V, W
Output terminals Used to connect the three-phase motor.
PE
Grounding terminal
(PE)
Protective grounding
Note
Terminals + and BR for the braking resistor are optional and are available only on models
with the letter "B" at the end. Models without the letter "B" do not have these terminals
and do not support external braking resistors.
