every 2 to 3 hours to recharge the battery system. This will guard against any unexpected
The inverter may be used whether or not the vehicle’s engine is running. However, the inverter may not operate while the engine is starting since the battery voltage can drop substantially during cranking.
The inverter draws less than 0.4 ampere from the battery when it is not supplying power to a load. In most instances, the inverter can be left connected to the battery when not in use since it draws so little current when the power switch is in the ON position. However, if the vehicle is to remain unused for several days, disconnect the inverter from the battery.
6.PROTECTIVE FEATURES OF THE INVERTER
Your MAXX 400 SST monitors the following potentially hazardous conditions:
LOW BATTERY VOLTAGE - This condition is not harmful to the inverter but could damage the power source. An audible alarm will sound when input voltage drops to 10.6. The MAXX 400 SST automatically shuts down when input voltage drops to 10.0 volts. When the condition is corrected, the unit may be restarted.
OVER VOLTAGE PROTECTION - The MAXX 400 SST will automatically shut down when the input voltage exceeds 15.5 volts DC.
SHORT CIRCUIT PROTECTION - Reverse polarity or a short circuit condition will usually result in an external fuse being blown.
OVERLOAD PROTECTION - The inverter will automatically shut down when the continuous draw exceeds 400 watts.
OVER TEMPERATURE PROTECTION - If the temperature inside the MAXX 400 SST is too hot to operate, the unit will automatically shut down. Allow the unit to cool for at least 15 minutes before restarting after a
LOW BATTERY ALARM - An alarm will sound when the voltage from the battery drops to 10.6 volts. This is an indication that the battery needs to be
