The DC breaker Q1 must be installed as the protection switch for PV input.
In parallel connection, the combination box special for PV must be used.
When the distance between the PV input component and VFD exceeds 10
meters, type-II surge protection devices must be configured at the DC
side.
When the distance between the pump and VFD exceeds 50 meters, it is
recommended to configure output reactors. See appendix A.4 for the
output reactor model selection.
The VFD automatically runs after being powered on. If parameters need to
be set, follow the parameter setting instructions in chapter 5.
Before connecting the braking resistor cable, remove the yellow labels of
PB, (+), and (-) from the terminal blocks. Otherwise, poor connection may
occur.
