3) Single-phase 200V power input
4) Single-phase 100V power input
*2. For installations in the United States or Canada, the circuit breaker must be inverse
time or instantaneous trip type.
*3. The power factor may be slightly lower.
*4. When the breaker on the inverter primary side trips, check for the wiring fault (short
circuit), damage to internal parts of the inverter, etc. Identify the cause of the trip,
then remove the cause and power on the breaker.
*5. The single-phase 100V power input model does not allow the power factor improving
DC reactor to be fitted.
