In the figure, the inverter is supposed to be capable of bidirectional power conversion from AC
to DC, from DC to AC, called a regenerative function, and supplies electric power converted
from AC to DC to EZA during battery charging.
Note) Since there is a male terminal of RJ45, you
can connect it to RJ45 of EZA and use as it is.
Considering CPU reset, maintenance, and troubleshooting, it is
recommended to insert NFB and magnet switch between the
battery and EZA, EZA and inverter respectively.
When the auxiliary power supply of EZA is activated, the
communication with EZA is possible with RS485 and the internal
parameter setting becomes possible.
