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.
Control power is supplied internally from the main circuit DC power supply for all Inverter models.

CIMR-G7B20P4 to 2015 and 40P4 to
4015
Be sure to remove the short-circuit bar before connecting the DC
reactor.
CIMR-G7B2018, 2022, and 4018 to 4045
The DC reactor is built in.
IMPORTANT
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.
CIMR-G7B2030 to 2110
CIMR-G7B4055 to 4300
IMPORTANT
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.
