1.2 Safety Requirements and Cautions ●Before Installation ●Installation ●Wiring 1 Danger 1. Only qualified personnel can operate the equipment. Before operating, be sure to carefully read the manual. The safe operation depends on the proper processes of choosing models, carrying, installation, operation and maintenance. 2. Don’t use the damaged or incomplete solar pump inverters; Otherwise, there is risk of injury. Danger 1. Please install the solar pump inverter on metal or other nonflammable material, and keep it away from the combustible material. Otherwise there is danger of fire. 2. No unauthorized modification to the solar pump inverter; Otherwise there is danger of damage. 3.

Normal solar pump inverter without explosion-proof cannot be installed where with explosive gas or dust; Otherwise there is danger of explosion. Danger 1. Wire is connected only when the main circuit is cut off, otherwise there is a danger of shock. 2. Wire is connected by professional person only. Otherwise there is a danger of shock. 3. Earth must be reliable. Otherwise there is a danger of shock. 4. DC power supply should not be connected to output terminals U, V, W, otherwise there is a danger of damage to solar pump inverter. 5.

No drop of bolt, spacer, metal stick, conducting wire or other things into the inner of solar pump inverter; Otherwise there is a danger of fire or damage to solar pump inverter. Attention 1. If the damage to solar pump inverter or other equipment is caused by improper wiring and utilization or unauthorized alteration, the user should shoulder all responsibilities.

SI30 Solar Pump Inverter Manual ●Before Electrification ●After Electrification 2 2. Please make sure all wirings meet EMC requirements and satisfy safety standards 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. Don’t touch the printed circuit boards, IGBT or other internal devices without anti-static measurements; otherwise it will cause the malfunction to solar pump inverter. 4.

Please don't connect phase shift capacitance or LC/RC noise filter to the output circuit of solar pump inverter; Otherwise it will damage the inverter. 5. Please don't connect the magnetic switch or magnetic contactor to the output circuit of solar pump inverter; When solar pump inverter is in the operation with load, magnetic switch or magnetic contactor can make inverter over-current protection act. It will damage solar pump inverter seriously. 6. Please don't dismantle the panel cover, and it only needs to dismantle the terminal cover when wiring. 7. It is forbidden to do any pressure test on solar pump inverter, otherwise it will damage the solar pump inverter. Danger 1.

Please make sure that voltage grade of power supply is consistent with solar pump inverter's rated voltage and then check whether the wiring is correct, and whether there is short circuit in peripheral equipment's circuit. Otherwise it will damage solar pump inverter and other equipment. 2. Before the solar pump inverter is connected to the input power supply, make sure that the cover has been well fixed. Otherwise it will cause electric shock. 3. For the solar pump inverters whose storage time is over 1 year, when electrification, the voltage should be raised by booster from low to high. Otherwise it will damage the solar pump inverter. Attention 1.

Check if all periphery fittings are wired properly according to the handbook; Otherwise it will cause accidents. 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 solar pump inverter with wet hand. Otherwise there is danger of damage to solar pump inverter and electric shock.

SI30 Solar Pump Inverter Manual ●Operation ●Maintenance 1.3 Cautions in Using 1. In application of this series solar pump 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 solar pump inverter's rating current (The rating current of the motor is far smaller than that of solar pump inverter), please adjust the protective value to ensure safe running. 3.

In occasions such as load raises, usually there is negative torque and solar pump inverter breaks off for over-current or over-voltage. In this case, you should consider choosing the matching brake unit. 3 Attention 1. Please set the parameter of solar pump inverter cautiously; Otherwise it will damage equipment. Danger 1. Before running, please check and confirm the application range of the machine and equipment 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.

Unprofessional workers are banned to check the signals in the running stage; Otherwise it will cause injuries and damage the equipment. Attention 1. Please don't turn off the equipment by switching off power; Please cut off the power supply after the electric machine stops running; Otherwise it will damage the solar pump inverter. 2. Please avoid anything dropping into the equipment when the solar pump inverter is running; Otherwise it will cause electric shock. Danger 1. Please don't maintain and repair the equipment with electric; Otherwise it will cause electric shock. 2.

Before maintaining and repairing the solar pump inverter, please make sure the indicator lights of power supply have completely turned off; Otherwise it may cause electric shock and damage the solar pump inverter. 3. Persons who have not passed specialized train are not allowed to conduct the solar pump inverter maintenance; Otherwise it may cause electric shock and damage the solar pump inverter.

4. Solar pump inverter, in a certain output frequency range, can meet the mechanical resonance of the SI30 Solar Pump Inverter Manual 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 solar pump 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 solar pump 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 multi-meter measurement, deviation of the reading will be great. And the deviation is different by using different type of digital multi-meter. Under normal circumstances, while RMS 380V, digital multi-meter reading is around 450V. 8.

Solar panel can be connected in series or parallel. For rated voltage 380V controller, we suggest solar panel open circuit voltage should be between 620~ 750V. 1.4 Technical Specification 1.5 Cautions in Disposal When you dispose solar pump inverter, please pay attention to: 1. Electrolytic capacitor: the electrolytic capacitor of main circuit or the printing plate may explode when they are burned. 2. Plastic: plastic incineration may generate toxic gases. 3. Dispose method: please dispose as industrial waste.
