Operating During Transition Between Shore Power and Inverter Mode

The allowable Freedom HF input voltage ranges are shown in the following table for Freedom HF 1500 and Freedom HF 1800 T:

Operating	Voltage Range	Voltage Range	Comment
Condition	Freedom HF	Freedom HF
	1500 only	1800 T only
Full Operating	Low, Mid, High:	Low:	Low refers to low limit of the low
Range	12.1–15.5 volts	10.5–15.5 volts	voltage threshold.
		Mid:	Mid refers to middle limit of the low
		11.8–15.5 volts	voltage threshold.
		High:	High refers to high limit of the low
		12.1–15.5 volts	voltage threshold.
Optimum	12.1–13.0 volts	12.1–13.0 volts
Performance
Low Voltage	Low, Mid, High:	Low: <11.0 volts	A silent low battery warning shows
Alarm	<12.6 volts	Mid: <12.3 volts	fault code  on the display.
		High:<12.6 volts
Low Voltage	Low, Mid, High:	Low: <10.5 volts	A single one-second low battery
Shutdown	<12.1 volts	Mid: <11.8 volts	alarm beeps and the display shows
		High:<12.1 volts	fault code . After five minutes,
			the unit shuts down completely.
Instant Low	<10.2 volts	<10.2 volts	After two seconds below the limit,
Voltage			the unit shuts down and the low
Shutdown			battery alarm sounds a long beep
			continuously for 30 seconds.
High Voltage	15.5 volts or	15.5 volts or	The over-voltage alarm beeps every
Shutdown	more	more	second and the display shows fault
			code  alternating with the battery
			voltage. The status LED turns red and
			the display screen is turned OFF
			within 30 seconds to protect itself
			from excessive input voltage.
			NOTE: Although the Freedom HF
			incorporates over-voltage protection,
			it can still be damaged if input
			voltage exceeds 16 volts.
