NOTE
• The terminals R/L1, S/L2, and T/L3 on the converter are control terminals to detect power phases of the power supply. For
wiring, the voltage phase must be consistent between terminals R2/L12, S2/L22, and T2/L32 and terminals R/L1, S/L2, and
T/L3. If these terminals are not connected correctly, the converter does not operate properly.
• If the inverter is operated while the converter terminals R/L1, S/L2, and T/L3 are not connected to the power supply, the
converter will be damaged.
