Main Circuit Configurations
The main circuit configurations of the Inverter are shown in Fig 2.5.
Table 2.5 Inverter Main Circuit Configurations
Note 1. Consult your Yaskawa representative before using 12-phase rectification.
Note 2. When installing a molded-case circuit breaker (MCCB) on the DC power supply side, do not use it to turn the Inverter power supply ON and OFF.
* These terminals are wired before shipment. When using DC power for the main circuit power supply, remove the wires between R-r/
