OVER TEMP Indicator (and Alarm)
The OVER TEMP LED (light emitting diode) and audible alarm indicate
that the inverter has shut itself down because it has overheated. The
inverter may overheat because it has been operated at power levels above
its continuous output rating, or because it has been installed in a location
that does not allow it to dissipate heat properly. The inverter will restart
automatically once it has cooled off.
OVER LOAD Indicator
The OVER LOAD LED indicates that the inverter has shut itself down
because of severe overload, an AC wiring fault or a short circuit.
If the
OVER LOAD LED comes on, turn off the On/Off switch, correct
the fault condition, and then turn the switch back on.
Do not turn the inverter on again until you have corrected the fault
condition.
Operating Limits
Power Output
The PROwatt 3000 can deliver 3000 watts (26 amps) for 5 minutes or
2500 watts (22 amps) continuously at 77º F (25º C) when the input
voltage is between 12 and 14 volts.
The wattage rating applies to resistive loads such as incandescent lights
while the current rating applies to reactive loads such as motors.
