Standard Connection Diagrams

Standard Inverter connection diagrams are shown in Fig 2.5. These are the same for both 200 V Class and
400 V Class Inverters. The connections depend on the Inverter capacity.

Be sure to remove the short-circuit bar before connecting the DC
reactor.
When connecting a separately-installed type Braking Unit (model CDBR), connect the B1 terminal of the
Inverter to the + terminal of the Braking Unit and connect the − terminal of the Inverter to the − terminal of the
Braking Unit. The B2 terminal is not used in this case.

Control power is supplied internally from the main circuit DC power supply for all Inverter models.
If a Braking Unit or a Braking Resistor Unit is connected to a wrong terminal, the Inverter, Braking Unit, or
Braking Resistor Unit can be damaged.
