Disconnect all power supplies applied to the inverter before the terminal
wiring and wait for at least the designated time after disconnecting the
power supply.
High voltage is present inside the inverter during running. Do not carry out
any operation except for the keypad setting.
The inverter automatically runs once power on. If parameters need to be
set, follow the guidelines in this chapter.
5.1 Inspection before operation
Before powering on the inverter, ensure that:
a) The inverter is grounded reliably.
b) The wiring is correct and reliable.
c) The AC/DC breaker is selected correctly.
d) The PV input voltage is in the allowed range of the inverter.
e) The type, voltage, and power of the motor match those of the inverter.
5.2 Trial run
Close the DC breaker. The inverter automatically runs with a delay of 10 seconds. Check the
water yield of the pump. If the water yield is normal, the trial run is successful. If the water yield
is under the normal value, exchange any two motor cables, connect the cables, and perform
trial run again.
5.3 Parameter settings
The inverter automatically runs by default once being powered on. If you want to set
parameters, press QUICK/JOG within 10 seconds since the inverter power-on to switch to the
keypad control mode (LOCAL/REMOT is off) and then set parameters. If the running indicator
is already on after the inverter is powered on, press STOP/RST to enter the parameter setting
mode. After parameter setting, turn off and then turn on the power switch. The inverter runs
again.
5.4 Advanced settings
Note: The default settings of the inverter for the water pump can apply to most conditions and
the advanced settings are not required in most cases.
5.4. PI adjustment to the water yield
If the user requires large or low water yield, it is necessary to adjust PI (P15.06~P15.10)
