IMPORTANT NOTE: The power inverter will not operate most appliance designed to produce
heat, such as hair dryers, coffee makers, irons, heaters, and toasters. The current use of most
of these exceeds rated power watts, far beyond the capacity of this unit. The inverter may be
used either while engine is running or turned off. However, the inverter may not operate while the
engine is st arti ng, since t he bat t ery vol tage can drop substantially during cranking.
The power inverter draws less than 1.3 ampere from the battery when it is not supplying
power to the load. In most cases, the power inverter may be left connected to the battery
when it is not in use, since it draws so little current. If the vehicle will not be used for several
days, disconnect the power inverter from the battery.
LOW BATTERY ALARM
An alarm will sound when the voltage of the battery drops to 10.5volts. This indicates that the
battery requires recharging. The user should stop operations at this time, since the power
inverter will shut down automatically when battery voltage drops to 10.0 volts.
If the low battery alarm sounds when the battery is fully charged, follow the steps for correcting
the lack of output power in the Trouble Shooting Guide. The alarm will sound when the
inverter is overloaded, or if there is an excessive voltage drop between the battery and the
inverter.
NOTE: The alarm may sound momentarily when the unit is being connected to, or
disconnected from, the power source. This is normal and does not indicate any problem.
