4.4.1 How to connect three phase load
In case of three-phase load:
Each electric current value of each phase (U
･
V
･
W) should not
exceed the values in the following table. But please note that
the data in the table is based on power factor of 80% (in case
of electric motor operated). In case of different power factor,
take care not to be overloaded, and reduce load.
Type Permissible current value
50Hz/200V 107A
60Hz/220V 118A
50Hz/380V 56.2A
50Hz/400V 53.4A
60Hz/440V 59.0A
In case inverter load:
The inverter capacity (input kVA of inverter) should not exceed the following value (within rated
output
÷
3.0). Also select generator so that the rated output (kVA) of generator so that the rated
output (kVA) of generator may be three times of the inverter capacity.
Example: In case of SDG45S,at 50Hz, 37kVA
÷
3.0 = 12.3kVA.
50Hz: 12.3kVA (Input kVA of inverter) It is possible to use inverter capacity up to this value.
60Hz: 15.0kVA (Input kVA of inverter) It is possible to use inverter capacity up to this value.
