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.
