Using a Battery for the DC Bus and 24 V Power Supply Unit Option for the Control Circuit
Follow the instructions when using a 24 V Power Supply Unit option for the control circuit and a battery for the main
circuit. The main circuit battery voltage must be higher than 48 Vdc for 200 V, 400 V, and 600 V class drives.
Yaskawa offers a 24 V Power Supply Option for the control circuit that is useful in applications unable to connect to a
backup battery greater than 250 V. Wiring instructions can be found in Figure 55 to Figure 57. For a more detailed
explanation of the 24 V Power Supply Option, refer to the manual provided with the option.
Wiring for CIMR-LU20008 to 20180, 40005 to 40112, and 50003 to 50077
