 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 cell module 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.
