Danger High Voltage
Directly touching or humid things indirectly touching would bring you in
danger.
- Do not take a part of the host machine without authorization! The input and output voltage of host machine is high danger voltage. It will bring you in danger by touching.
- Must switch off the electrical power before maintaining. Itis better-using a voltmeter to check the host machine output end before maintaining to make sure the electrical power off.
- Even though all the external electricity is powered off, the residual charge is still on the internal of the inverter. Please keep inverters stewing for time ≥ 10 min to make sure the charge is gone before opening the shell of the host machine.
- Please keep the machine insulated before installation and use.
- Do not take with any electric conduction processing for example, watches, bracelets or rings.
- The inverter fixing and maintenance are only for professional servicemen.
Inductive load and half-wave rectification load attention
Please choose inverters as 2 to 3 times of load power when hitching half-wave
rectification or inductive load.
Static avoiding
Please wear the antistatic wrist strap and use the other side to connect the
ground for protecting the sensitive part of the machine from personal static
before touching it.
Do not take apart the machine under power ON
Do not install and take off the power line when the electricity is on. Please
connect the wires as the countermark shows.
Use only regulation battery
The product would be failure with a non-regulation battery.
Operate the battery as instructed
Must install the battery as shown in the inverter installation instructions.
- Do not connect the wires in short circuit. Must keep the connector tight. Do not touch any the of connectors of the battery at the same time or the wires exposed sides.
- Avoiding the electrolyte of battery overflow. The electrolyte would cause metal corroding, machine fault, and short circuits.
- Keep battery away from the fire or any easy-to-cause spark machines
Caution! Fans!
Wait until fans are completely stopped. Do not use your fingers or other
objects to stop the fans.
Mount the device in a well-ventilated space
Make sure the air intake and exhaust are not blocked in any way. Also, do not
mount the top side of the passive cooling radiator too close to any wall or
panel, so the air flows freely.
INVERTER INSTALLING
Check the box contents
Please check things following after opening the package:
Check the inverter outside if has any damage. If there is any damage of the
machine, please contact the common carrier immediately.
Check if the standard accessories are complete. If you find out any missing
accessory or wrong model please contact your supplier immediately.
Installation environment
Keep inverters in well-ventilated places. Keep inverters away from water,
overheating, explosives, direct sunlight, volatile gas and over salinity.
Caution
The operating temperature range of the inverter is -26•80˚C. Do not overload
the inverter, and it’s not recommended to use over 40˚C. If the inverter
temperature is over 40˚C, reduce consumption with 10% for every 1˚C over 40.
The best operating temperature range for the battery is -20˚C•30˚C. If the
temperature is over 30˚C, the battery life span will drop. Under 20˚C the
electric storing time will drop.
Safety using distance
The inverter must pe mounted at least 60mm from the front and back panel to
anything nearby. Please do not cover the two-panel sides of the inverter to
avoid overheating and reduce the life span.
Electric cable connection
Caution
Please make sure the inverter power button is off before connecting the
cable. Do not make the wrong connection of polarity, or would cause an
inverter short circuit. Please do as the following sequential process when you
connect the inverter cable:
- Turn the power button to “OFF”.
- Connect the direct current input cable to the polarity of the battery.
- Make sure the plugs of the inverter and battery are tightly connected or would cause the cable to overheat.
- Connect a load to the power outlet of the inverter on the side panel.
- Ensure all the connections are properly done, turn on the inverter. If the green LED lights on, then the output voltage is correct and the device is ready to use.
The correct connection is shown in the below picture.
Cautions
- Do not use the alternating current output to connect the power grid, or would cause frying the inverter.
- Make sure the power loads increase gradually and do not go over the rated power of the inverter.
- For inductive loads use an inverter 2-3 times its power.
- Because the vacuum pump and electromotor start current is too strong, the inverter should be turned off when you start the car.
- The inverter should be kept in well-ventilated places, not covered by anything, and kept away from touching it.
- Do not connect the inverter to discharged or old batteries, or it will cause frying the inverter.
Installation environment
- Keep the inverter in a well-ventilated and clean place.
- Keep inverters away from water, direct sunlight, dirt, and fog.
- The operating temperature is -26˚C•80˚C.
ABOUT BATTERY
Storage battery introduction
A storage battery is a device of chemical energy change to electrical
energy and a device of inverter input. Choose a suitable battery corresponding
to the inverter model to ensure optimal functioning.
Storage battery performance index
- 1. Capacity: Represents how much energy at full power equals the discharging current multiplied by discharging time.
Capacity = discharge current (I) x discharge time (H)
2. Discharge rate: The speed of each discharge current.
3. Discharge current: Discharge current is the output current. It is usually expressed by ampere or volume multiplied by some coefficient.
4. Final discharging voltage: It means the voltage when the battery is not going to discharge; it is usually I. 75V/unit cell
5. Nominal capacity: It means the capacity after 20 hours of discharge.
6. Self-discharge rate: The battery would discharge without use.
The unit is C/unit.
Choosing the right battery
Because inverters need a strong current when it is working, the capacity it, if the capacity of the battery and max output current are not enough, would cause the inverter can not to be derived fully loaded. Also, it would cause damage to the battery. The storage battery capacity depends on max discharge current: Max discharge current=rated power/(storage voltage0.85) Storage battery capacity=most discharge currentdischarging time.
Example:
- PNI L1200W Inverter rated power is 1200W, input voltage is 12V, so:
- Most discharge current=l200/(12*0.85)=117 A;
- If kept working for 2 hours:
- Storage battery capacity=l17*2=235AH
- Please choose a battery with a capacity higher than 235AH.

2. Load lauch power is over inverter peak power. Inverter enters protection.
3. Low battery voltage. Inverter enters low voltage protection.
4. High battery voltage. Inverter enters high voltage protection.
5. Inverter temperature is too high.
| 1. Reduce load.
2. Inductive load (motors, pumps) have a high consumption at launch. Choose a inverter 4-5 times more powerfull in these cases.
3. Ii the battery voltage goes over the minimum protection level, the inverter restarts automatically (or replace the battery).
4. Daca voltajul bateriei scade sub nivelul maxim de protectie, invertorul reporneste automat(sau schimbati bateria).
5. Turn off the inverter for 15 min, Check and clean the fans and the air intakes and keep a venting space around.
Inverter not working in full load| 1. The cables between battery and inverter are too long
2. Cable connection is loose.
| 1. Shorten the cables or use thicker.
It’s recomended to use the cables in the box.
2. Check the cable connection and tighten them up.
If the inverter cannot work despite those problems, please contact the agency or manufactory immediately. Do not disassemble the inverter by yourself, the warranty will be void.
