■ 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 class drives and 96 Vdc for 400 V class
drives.
Wiring
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 4.27 . For a more detailed explanation of
the 24 V Power Supply Option, refer to the manual provided with the option.

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.
