120 Volt AC Power Outlets
RATED VERSUS ACTUAL CURRENT DRAW OF EQUIPMENT
Most electrical tools, appliances, electronic devices and audio/visual 
equipment have labels that indicate the power consumption in amps or 
watts. Be sure that the power consumption of the item to be operated 
is below 1000 watts. If the power consumption is rated in amps AC, 
simply multiply by the AC volts (120) to determine the wattage.
Resistive loads are the easiest for this unit to run; however, it will not 
run larger resistive loads (such as electric stoves and heaters), which 
require far more wattage than the unit can deliver on a continuous 
basis. Inductive loads (such as TVs and stereos) require more current 
to operate than do resistive loads of the same wattage rating.
POWER INVERTER OUTPUT WAVEFORM
The AC output waveform of this unit is known as a modified sine wave. 
It is a stepped waveform that has characteristics similar to the sine wave 
shape of utility power. This type of waveform is suitable for most AC 
loads, including linear and switching power supplies used in electronic 
equipment, transformers, and small motors.
PROTECTIVE FEATURES
The unit monitors the following conditions:
Low internal battery voltage: The unit will automatically shut down 
when the battery voltage drops too low, as this can harm the battery.
High internal battery voltage: The unit will automatically shut down 
when the battery voltage is too high, as this can harm the unit.
Thermal shutdown protection: The unit will automatically shut down 
when the unit becomes overheated.
Overload/short circuit protection: The unit will automatically shut 
down when an overload or short circuit occurs.
Important Notes Concerning the AC Power Outlets
  1. The two AC Power Outlets provide a combined total power draw 
of 1000W.
 2. When the AC Power Outlets are in use, the unit will monitor for 
the following fault conditions: thermal fault, low and high battery 
voltage fault, overload and short circuit (refer to the “Protective 
Features” section). If a fault condition exists in either of the AC 
Power Outlets, AC Power Outlets will shut down automatically 
and the backlit LCD screen will continuously display the following:
    The Battery Status Icon lights solid and the Digital Display will show 
“0”; the Wattage Indicator and Fault Icon on the LCD Screen will 
flash. Should this occur:
   a. Disconnect all appliances from the unit.
   b. Press the AC Power Button to turn the AC Power Outlets off.
   c. Make sure the unit does not need to be recharged.
   d. Allow the unit to cool down for several minutes.
    e.  Make sure the combined rating of all appliances plugged into 
the unit is 1000 watts or lower and that appliance cord(s) and 
plug(s) are not damaged.
   f.  Assure there is adequate ventilation around the unit before 
proceeding.
USING THE DUAL 120 VOLT AC OUTLETS
The two 120 Volt AC Outlets are located on the front of the unit (refer 
to Fig. 2 to locate). The two outlets support a combined maximum 
power draw of 1000 watts.
