■
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
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
