■ Using Separate Batteries for DC Bus and Control Power Supply, DC Bus Battery under 250
Vdc (500 Vdc, 720 Vdc)
Follow these instructions when using separate batteries for Rescue Operation with the battery for the DC bus having a
lower voltage than 250 Vdc for 200 V class drives, 500 Vdc for 400 V class drives, or 720 Vdc for 600 V class drives.
Follow the wiring diagram shown in Figure 4.22 to Figure 4.24. When connecting the battery for the control power
supply to the L1000A, use the 1.1 m cable packaged with the product. The connector cover must first be removed in order
to access connection port CN19 for the battery. Refer to Connecting the Drive and Battery on page 145 for details.
