IMPORTANT SAFETY INSTRUCTIONS

• When replacing the batteries, use the same number and the same type of batteries.
• Do not dispose of batteries in a fire; the battery may explode.
• Do not open or mutilate te the battery or batteries, released electrolyte is harmful to the skin and eyes.
• A battery can present a risk of electric shock and high short circuit current. The following precautions should
• Batteries will be disposed of by the manufacturer or importer. Customers need to send them back with no charge for disposal. voltage still may be accessible through supply of the battery.
• The battery supply should be therefore disconnected in the plus and minus pole through or from the outer enclosure accessible battery fuses when maintenance or service work inside the inverter is considered.
• The lead-acid battery may cause chemical hazards.
• The battery presents a risk of electric shock and energy hazards.

TROUBLESHOOTING

2.  Breaker broken.

3.  Dead wall socket.

| 1. Check the line cord plug.

2. Replace the breaker.

3. Check wall socket with a table lamp.

Power output is normal, inverter emits continuous beep, Load level indicator

flickers

| Inverter is overloaded| Turn off the inverter and unplug excessive loads from the inverter.

The inverter does not provide the expected run time.

| 1. Excessive loads connected inverter’s outlets

2. Battery is weak and can not provide enough

| Do not operate the inverter. Leave the inverter

plugged in for 10 hours. Then test it again. If the inverter still can not provide the expected run time, battery should be replaced.

Buton on the front panel doesn’t work.

| 1.   The CPU inside the inverter is not running correctly.

2.   Buton damaged.

| Unplug line cord and battery cord from the inverter to let it shut down automatically, and plug line cord and battery cord again, if button still fails, please call for service.
The inverter emits urgent beep, Battery capacity indicator

| Low battery| 1. Charge bateries.

2. Replace bateries.

3. Call for service.

Inverter cannot DC start

| 1. Battery polarity wrong.

2. Battery wrong (over-voltage).

3. Battery exhaustion.

4.  Inverter fault.

| 1. Check the battery and connection.

2. Check battery voltage by a voltage meter.

3. Connect the AC power cord to charge the battery.

4. Call for service.

OPERATION OF INVERTER

SAVE THESE INSTRUCTION. This manual is important instructions that you should follow during the installation and maintenance of the inverter and batteries. Please read all instructions before operating the equipment and save this manual for future reference.

1. Connect the RED battery cable to the anode and the BLACK one to the cathode. Battery cables are required to be connected with the anode and cathode tightly. Short circuits between the anode and cathode, as well as the polarity reverse, are strictly forbidden.
2. Connect your equipment to the inverter. To ensure that your equipment will be protected during a utility failure, it is important to make sure that the maximum power needed by the equipment is not over the rated capacity of the inverter. The alarm will beep if the load is over the rated value. Meantime, if the overload is severe, the inverter will shut down immediately to protect itself.
3. DC start: During a blackout, push the button for 4 seconds; then, the inverter will be turned on and enter into back-up mode. To turn off the power from the inverter; please push the button for 4 seconds.
4. Once it’s connected with normal city power, the inverter will charge the battery automatically, Please push the button on the front panel for about 4 seconds to turn on the inverter.
5. Pushing the button for 4 seconds to turn off the inverter. The inverter will keep charging the battery if the utility power is normal. Please pull out the power cord if you want to turn off the inverter completely.
6. Under backup mode, when the battery voltage is too low or too high, the inverter will emit an alarm; if the voltage is too low/high, the inverter will turn off automatically.

FRONT PANEL

Electronic and electrical equipment marked with the above symbol should be recycled again. Used equipment with this marking should be returned to its manufacturer/importer/supplier or to collection centres for used electrical and electronic equipment. At the same time, the above label means that the equipment was placed on the market after August 13, 2005. Waste electrical and electronic equipment is not only waste that is often hazardous to the environment, which may contain substances, mixtures and hazardous components but at the same time a material from which valuable raw materials such as iron, copper, tin, glass and even gold and silver can be recovered. Proper handling of waste electrical and electronic equipment will help protect the environment and human health from the negative consequences resulting from the possibility of hazardous components in the equipment.

FAQ

Q: What should I do if the inverter emits an urgent beep and the battery capacity indicator shows low battery?
A: Charge the batteries immediately. If the issue persists, consider replacing the batteries or contacting customer service for assistance.

Q: How can I troubleshoot if the inverter does not start in DC mode?
A: Check the battery polarity and connection, verify the battery voltage, charge the battery using AC power if needed, and if the problem continues, contact customer service for further support.
