YASKAWA TOEPYAIL1E01A YASKAWA AC Drive L1000E Quick Start Guide

Wiring for CIMR-LE2A0269 to 2A0432, 4A0188 to 4A0260

• Voltage lower than 48 to 190 Vdc for 200 V class drives, 48 to 380 Vdc for 400 V class drives

Figure 63 Using a Battery for the DC Bus and 24 V Power Supply Unit Option for the Control Circuit

(CIMR-LE2A0269 to 2A0432, 4A0188 to 4A0260)

Refer to

Table 31

for the installation of the inrush current suppression circuit for battery.

<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.
