• Voltage Lower Than 48 to 190 Vdc for 200 V Class Drives, 48 to 380 Vdc for 400 V Class Drives, and 48 to 500 Vdc
for 600 V Class Drives

Figure 55 Voltage Lower Than 48 to 190 Vdc for 200 V Class Drives, 48 to 380 Vdc for 400 V Class Drives,
and 48 to 500 Vdc for 600 V Class Drives
<1> Install the inrush current suppression circuit outside the drive if the DC bus battery voltage is lower than 190 Vdc for 200 V class drives
and 380 Vdc for 400 V class drives. Failure to comply will cause the soft-charge bypass relay to remain open and result in damage to the
drive.
