CIRCUIT PROTECTION
TO PROVIDE ADDED SAFETY FEATURES
Ⅰ. OVER TEMPERATURE PROTECTION
If the temperature inside the inverter istoo high, the unit will automatically shut down. Allow the unit to cool for at least 15 minutes before restarting. Unplug unit while cooling. For Pooxtra inverter, the value of over temperature shutdown protection has been set to 88℃ or 190℉
Ⅱ. LOW DC INPUT VOLTAGE SHUTDOWN PROTECTION
This condition is not harmful to the inverter but could damage the power source.The Pooxtra inverter automatically shuts down when input voltage drops to 10.0 volts. (for 12V DC Input )
Ⅲ. LOW DC INPUT VOLTAGE AUDIBLE ALARM
An alarm will sound when the DC input voltage from the battery drops to 10.5 volts. This is an indication that the battery needs to be recharged. The user should stop operation of the electronic device at this time since the inverter will shut down shortly thereafter, when the battery voltage drops to 10 volts. Start your engine to recharge the battery.
NOTE: It is normal for the alarm to sound while the unit is being connected to, or disconnected from the power source. This is not indicative of a problem.
Ⅳ. HIGH DC INPUT VOLTAGE SHUTDOWN PROTECTION
The Pooxtra inverter will automatically shut down when the input voltage exceeds 16.0 volts DC. Input voltage exceeding 16 volts could damage the inverter. (for 12V DC Input )
Ⅴ. HIGH DC INPUT VOLTAGE AUDIBLE ALARM
The Pooxtra inverter will automatically have an audible alarm when the input voltage exceeds 15.5 volts DC. It mentions to you that the DC input voltage is too high to be warned and to be taken action immediately . (for 12V DC Input )
NOTE: It is normal for the alarm to sound while the unit is being connected to, or disconnected from the power source. This is not indicative of a problem.
Ⅵ. OVERLOAD PROTECTION
The inverter will automatically shut down when the continuous draw exceeds rated watts.
Ⅶ. SHORT CIRCUIT PROTECTION
The inverter will shut down. Remove the short circuit and restart inverter.
Ⅷ. EARTH FAULT PROTECTION
This inverter complies with the standard current leakage allowance. When large current leakage to earth terminal occurs,the protection circuit is activated and shuts down the inverter, which prevents electric shock.
