protected against overheating. It will provide its full rated output up to
the temperature listed in the specification sheet. If it is subjected to
higher ambient temperatures or air circulation is blocked, the inverter
may overheat. If the LOWBATT/ THERM buzzer sounds, immediate
action is required or the inverter will shut down. Either reduce load, or
provide more cooling in the immediate environment. If no action is
taken, the inverter will likely shut down within 2 minutes. When the
inverter shuts down, the alarm condition will persist. Since the
inverter has eliminated its load, it will cool fairly quickly. It will
automatically restart when it has cooled sufficiently, and the LOW
BATT/THERM alarm will clear. "105 C internal temperature. Warning
buzz 5 C before shut off".
If output power is exceeded, output voltage is reduced to a level
which will provide the inverter's rated power to the load by clipping
tops of the waveform. The inverter can operate safely in this mode
indefinitely. The overpower protection circuit will recover instantly
when the overpower condition clears.
