 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.
Fig 2.5 Main Circuit Terminal Connections
CIMR-G7A20P4 to 2015 and 40P4 to
4015
Be sure to remove the short-circuit bar before connecting the DC
reactor.
CIMR-G7A2018, 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-G7A2030 to 2110 CIMR-G7A4055 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.
Refer to FOR YASKAWA AC Drive Option Braking Unit, Braking Resistor Unit Installation Manual (TOB-
PC72060000) for connecting the Inverter with a Braking Unit or a Braking Resistor Unit.
