■ 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 4.25 to Figure 4.27. 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

Operation Sequence
Starting Rescued Operation
1.
Open contactor B and wait at least 5 seconds.
2. Set the input terminal programmed for Rescue Operation (H1- = 55).
3. Close contactors A and C.
4. Set the Up/Down command.
Ending Rescue Operation
1.
After the car has stopped, open contactors A and C.
2. Clear the input terminal set for Rescue Operation (H1- = 55).
3. Wait at least 0.5 s and then close contactor B to return to operation with normal power supply.
