4.When the inverter is working, if the alarm beeps, the indicator LED would take red, which means the inverter is faulty. Corresponding fault can be identified as shown in the section "Security feature". After fixing the fault, you can restart it.
Security features:
There are full protection and audio-visual alarm system in DF-SUN 600PSW power inverter. It can provide a full range of protection, mainly over-voltage protection, low-voltage alarm, under-voltage protection, over-heat protection, overload protection, short circuit protection, reverse polarity protection etc.
Protection and alarm sound definition:
. Low-voltage alarm: When the input DC voltage is lower than low-voltage alarm voltage, low battery alarm will remind the user that there is less power, but the power inverter can still continue to work. The alarm sound is the long sound "beep --- beep ... ...."
. Under-voltage protection: When the input DC voltage is lower than the cut off under-voltage, the power inverter output will be cut off automatically .Sound alarms "beep-beep-beep --- beep- beep-beep ... ...." When the input voltage returned to the normal input voltage, the inverter will restart output automatically. If the input voltage immediately returned to normal after alarm, the alarm sound will continue to sound about 30S and then restart the output.
. Over-voltage protection: When the input DC voltage is higher than the cut off over-voltage, the power inverter output will be cut off automatically. Sound alarms "beep-beep-beep --- beep- beep-beep ... ...." When the input voltage returned to the normal input voltage range, the inverter will restart output automatically. If the input voltage immediately returned to normal after the alarm, the alarm sound will continue to sound about 30S and then restart the output.
. Over-heat protection: When the internal temperature of power inverter is too high (above about 85℃), the power inverter output will be cut off automatically. Sound alarms "beep-beep-beep-beep--- beep-beep-beep-beep ... ...." Need to restart manually.
. Overload protection: When the power of electric apparatus which are driven by the power inverter exceeds the inverter's maximum output, the output would be cut off automatically. Sound alarm "beep-beep---beep-beep ... ...." Need to restart manually.
. Short-circuit protection: When the output short-circuited, or the loads are very big, the power inverter output will be cut off automatically. Sound alarms "beep-beep-beep-beep-beep---beep-beep-beep-beep-beep... ...." Need to restart manually.
. Reverse polarity protection: When the input positive and negative pole of the power inverter was connected reversed, it will fuse down the inverter's fuses to protect the internal circuits. After the replacement of fuses, inverter can work properly.
Working environment:
1.Operation temperature: -10℃~40℃.
2.Storage temperature: -40℃~65℃.
3.Considerable air humidity should be less than 85%.
4.No electrical conductivity, dust explosion, corrosion-free gas in the working place.
5.No shock and vibration in the working place.
