Note:
⚫ The 380V 132kW and higher inverter models can be connected to external DC reactors. Before
connection, remove the copper bar between P1 and (+). The 380V 132kW and higher inverter
models can be connected to external braking units. DC reactors and braking units are optional
parts.
⚫ The 380V 18.5kW–110kW (inclusive) inverter models are equipped with built-in DC reactors.
⚫ The 380V 37kW and lower inverter models carry built-in braking units, which are optional for the
45kW–110kW (inclusive) models. The models with built-in braking units can also be connected to
external braking resistors. Braking resistors are optional parts.
