PV500 series solar pumping inverters
● 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 inverter exceeds
10 meters, type-II surge protection devices must be configured at the DC
side.
● When the distance between the pump and inverter exceeds 50 meters, it is
recommended to configure output reactors. See appendix A.4 for the
output reactor model selection.
● The inverter 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.
