High-function General-purpose Inverter RX2 Series User’s Manual
Take a mechanical interlock for MC3 and MC2. Otherwise, you run the risk of damage to the inverter.
Since the commercial circuit does not operate either when the earth leakage circuit breaker (ELCB)
trips, connect the commercial circuit of another system to MC2 if the backup is required.
