Parameters setting:
F0.03=8(PV setting);
F0.11=4(keyboard+ terminals+ Communications)；
F1.00=1(forward run)；
F1.01=8(freewheel)；
F1.10=2(three-wire mode 1);
F1.40=1(input terminal can repeat the definitions);
E3.02=3(three-wire operation control)；
E3.05=00100；
E0.00=2(MPPT mode)；
F1.35=00000
Mark: If the water tower is set to switch value detection, the well is also set to switch value
detection. Set F1.40 to the input terminal which can be reusable definitions.
4-4.Wiring Precautions
Make sure that the power switch is in the OFF state before wiring operation, or electrical shock
may occur!
Wiring must be performed by a professional trained personnel, or this may cause damage to the
equipment and personal injury!
Must be grounded firmly, otherwise there is a danger of electric shock or fire hazard !
Make sure that the input power is consistent with the rated value of inverter, otherwise which
may cause damage to the inverter!
Make sure that the motor matches the inverter, otherwise which may cause damage to the motor
or activate the inverter protection!
Do not connect power supply to U, V, W terminals, otherwise which may cause damage to the
inverter!
Do not directly connect braking resistor to DC bus (P), (+) terminals, otherwise which may
cause a fire!
The U,V,W output end of inverter can not install phase advancing capacitor or RC absorbing
device. The inverter input power must be cut off when replacing the motor
Do not let metal chips or wire ends into inside the inverter when wiring, otherwise which may
cause malfunction to the inverter.
Disconnect motor or switch power-frequency power supply only when the inverter stops
output
In order to minimize the effects of electromagnetic interference, it is recommended that a surge
