to the nominal load. Measure the currents at the output of each module on phase T. If this current varies by more than ± 1% for this module, fine adjustment can be made with P1 on the IPR pcb.

Check the currents at the output of each module on phase S. These currents must be balanced to within ± 1% by finely adjusting the inverter voltage of phase S (P4 on ICT-2). i.e. If the module is supplying more current than the system average, the inverter voltage of this module must be reduced slightly.

Repeat for phase R currents by finely adjusting the R phase inverter voltage of this module with P3 on the ICT-2 pcb until the currents on the phase R of all modules are equal to within

± 1%.
