DCR: DC reactor
*1 Use crimp terminals covered with an insulated sheath or insulating tube. Recommended wire sizes are
for HIV/IV (PVC in the EU).
*2 Wire sizes are calculated on the basis of input RMS current under the condition that the power supply
capacity and impedance are 500 kVA (50 kVA for single-phase 100 V class series) and 5%, respectively.
*3 For single-phase 100 V class series of inverters, use the same size of wires as used for the main circuit
power input. Insert the DC reactor (DCR) in either of the primary power input lines. Refer to Chapter 10
for more details.
