1. Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage. Line
voltage drop is calculated as follows:
Line voltage drop (V) =
IMPORTANT
2. Use a closed-loop connector (made by J.S.T. Mfg. Co., Ltd. or an equivalent) for the main circuit input and
output terminals of Inverters of 200V 11 kW or more and those of 400V 22 kW or more.
