Note 1: For 200V-55kW, 400V-90kW or larger model, be sure to install DC reactor.
However, this is unnecessary for DC input specifications.
Note 2: Capacity is calculated at 220V for the 200V models and at 440V for the 400V models.
Note 3: An external power supply backup available (optional) (Type: CSP002Z)
Note 4: ±10% when the inverter is used continuously (load of 100%).
Note 5: Models, 200V-18.5kW or more and 400V-22kW or more, do not have wiring port covers. They have large
openings, but there is no space to bend the external cables inside the unit.
Note 6: Three-phase 380~480V-50/60Hz for 4900PC
