every 2 to 3 hours to recharge the battery system. This will guard against
any unexpected shut-down of the equipment and will ensure that there is
always sufficient battery capacity to start the vehicle’s engine. The inverter
will sound it’s alarm when DC voltage drops to 10.6 volt.
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 heat-related
shutdown. Unplug unit while cooling.
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
