Note:
1. 132kW and above inverters can be connected to external DC reactors. Before connection, it is
required to take off the copper bar between P1 and (+). 132kW and above inverters can be
connected to external brake unit. DC reactors and brake units are optional parts.
2. 18.5kW–110kW inverters are equipped with built-in DC reactor.
3. 37kW and below models carry built-in brake units, 45kW–55kW supports built-in brake unit.
75kW–400kW supports external brake unit. The models that carry built-in brake unit can also be
connected to external brake resistor. The brake resistor is optional part.
