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/
for 200 V Class Inverters, input 200 VAC to r/
400/ 400.
