utilization or unauthorized alteration, the user should shoulder all responsibilities.

2. Please make sure all wirings meet EMC requirement and satisfy safety standard in the local

area; Please refer to recommendations in this manual or national standards of wire diameter
to avoid accidents.

3. Static electricity on human body would seriously damage internal MOS transistor, etc. No

touch the printed circuit boards, IGBT or other internal devices without anti-static measure,
otherwise it will cause the malfunction of frequency inverter.

4. Please don't connect phase shifter capacitance or LC/RC noise filter to the output circuit of

frequency inverter; Otherwise it will damage the frequency inverter.

5. Please don't connect the magnetic switch or magnetic contactor to the output circuit of

frequency inverter; When frequency inverter is in the operation with load, magnetic switch or
magnetic contactor can make inverter over-current protection function act. It will damage
frequency inverter seriously.

6. Please don't disassemble the panel cover, it only needs to disassemble the terminal cover

when wiring.

7. It is forbidden to do any pressure test on frequency inverter, otherwise it will damage the

frequency inverter.

●Before electrification

Danger

1. Please make sure that voltage grade of power supply is consistent with frequency inverter's

voltage and then check whether the wiring is correct and firm, and whether there is short
circuit in peripheral equipment's circuit. Otherwise it will damage frequency inverter and other
equipments.

2. Before the frequency inverter is connected to the input power supply, make sure that the

cover has been fixed well. Otherwise it will cause electric shock.

3. For the frequency inverters whose storage time is over 1 year, when electrification, the

Solar Pump Controller Manual

voltage should be raised by booster from low to high. Otherwise it will damage the frequency
inverter.

Attention

1. Check all periphery fittings are wired properly according to the handbook; Otherwise it will

cause accidents.

●After electrification

Danger

1. After electrified, it is forbidden to open the cover, make wiring, and check up; Otherwise, it will

cause the danger of electric shock.

2. After electrified, it is forbidden to contact internal wiring board and its parts. Otherwise it will

cause the danger of electric shock.

3. Do not operate or touch frequency inverter with wet hand. Otherwise there is danger of

damage to frequency inverter and electric shock.

Attention

1. Please set the parameter of frequency inverter cautiously; Otherwise it will damage
equipment.

●Operation

Danger

1. Before running, please check and confirm the application range of the machine and
equipments once more; Otherwise it will cause accidents.

2. Please don't touch the cooling fan and braking resistance to check the temperature;
Otherwise there is a danger of getting burn.

3. Persons who have not passed specialized train are not allowed to conduct the frequency
inverter maintenance; Otherwise it may cause electric shock and damage the frequency
inverter.

1.3 Cautions in utilization

1. In application of this series frequency inverter, you have to confirm all machine insulation to
prevent damage to the equipment. Moreover, when the motor working in tough environment,
please periodic inspect the electrical insulation to ensure the safety of the system work.

2. If the motor adapter is not consistent with frequency inverter's rating current (The rating current
of the motor is far smaller than that of frequency inverter), please adjust the protective value to
ensure safe running.

3. In occasions such as load raising, usually there is negative torque and frequency inverter
breaks off for over-current or over-voltage. In this case, you should consider to choose the
matching brake unit.

4. Frequency inverter, in a certain output frequency range, can meet the mechanical resonance of
the load equipment. To avoid it, you can set up jumping frequency.

5. As output voltage of the inverter is pulse-wave type, if there is capacity which can improve
power factor or pressure-sensitive resistance which used for thunder-proof in the voltage
output side, the frequency inverter will break off or its parts will be damaged, so it is necessary
to dismantle them. Moreover, it is proposed not install switch parts like air switch and contactor
(if it is necessary to install switch on output side, please make sure the output electricity of
frequency inverter is zero when the switch is working)

6. At over 1,000 meters altitude, the inverter’s heat dissipation function worsened due to the thin
air, it is necessary to use less.

7. The inverter output voltage is pulse wave type. If using digital multimeter measurement,
deviation of the reading will be great. And the deviation is different by using different type of
digital multimeter. Under normal circumstances, while RMS 380V, digital multimeter reading is
around 450V.

8. Solar panel: many panels string or parallel. For rated voltage 380V controller, we suggest
working voltage between 480V to 560V while MPPT. What means the solar panel open circuit
voltage between 600V to 700V.
