Chapter 1 Safety Requirement and Cautions
To ensure safety of your health, equipment and property, please read this chapter carefully before
using the solar pump inverter and act in compliance with the instructions when installing, debugging,
running and overhauling the inverter.
1.1 Safety Definition
Danger: it will cause danger of serious injuries and even death while operating against the rules.
Caution: it will cause danger of light injuries or equipment destruction while operating against the
rules.
Note: some information is useful while operating and using solar pump inverter.
1.2 Safety Requirements and Cautions
● Before Installation
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.
● Installation
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.
● Wiring
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.
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.
● Before Electrification
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.

SI30 Solar Pump Inverter Manual

● 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 solar pump inverter with wet hand. Otherwise there is danger of
damage to solar pump inverter and electric shock.
Attention
1. Please set the parameter of solar pump inverter cautiously; Otherwise it will damage
equipment.
● Operation
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.
● Maintenance
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.

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.
4. Solar pump 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 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 620V~750V.

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.
