3.2.1 Identification of the Power Terminals and Grounding Points

The power terminals can be of different sizes and configurations, depending on the model of
the inverter, according to
control connections are shown in
Description of the power terminals:
L/L1, N/L2 and L3 (R, S, T): AC power supply. Some models of voltage 200-240 V (see
„
option of models in
three-phase inverters) without derating of the rated current. In this case, the AC power supply
can be connected to two of the three input terminals without distinction. For the single-phase
models only, the power voltage must be connected to L/L1 and N/L2.
U, V, W: connection for the motor.
„
-UD: negative pole of the voltage of the DC bus.
„
BR: connection of the brake resistor.
„
+UD: positive pole of the voltage of the DC bus.
„
DCR: connection to the external DC link inductor (optional). Only available for models 28 A,
„
33 A, 47 A and 56 A / 200-240 V and 24 A, 31 A, 39 A and 49 A / 380-480 V.
The maximum torque of the power terminals and grounding points must be checked in
