Trouble Loads
Some appliances, including the types listed below, may be damaged if
they are connected to the Freedom HF:
• Speed controllers found in some fans, power tools, kitchen appliances, and
other loads may be damaged.
• Some chargers for small rechargeable batteries can be damaged. See
“Precautions for Using Rechargeable Appliances” on page xi for details.
• Metal halide arc (HMI) lights can be damaged.
Over-temperature Conditions
During Inverter mode, when the Freedom HF’s internal temperature starts
to approach its preset shutdown limit, the alarm will beep every two
seconds and the display will show fault code E07. If the over-temperature
condition persists, the alarm will beep once per second and the display
will show fault code E04. The Status LED turns solid RED and the
inverter will shut down to prevent damage to the inverter and protect the
battery from being over-discharged. However, when the internal
temperature drops and falls within normal operating temperature, the
Freedom HF will recover automatically and will continue inverting.
During AC shore power mode, when the Freedom HF’s cha rger
temperature starts to approach its limit, the charging current will be
reduced to 10A (Freedom HF 1000) or 20A (Freedom HF 1800).
The Freedom HF also monitors the internal transfer relay temperature. It
automatically turns on the fan when the relay starts to approach its preset
temperature limit and turns off when it cools down. If the relay exceeds
its preset temperature limit, the display shows a fault code E11. See “To
reset error codes E10 to E12:” on page 5–7.
STATEMENT OF HAZARD
Some equipment may be damaged by the Freedom HF’s modified
sine wave output, which has a different wave form than utility-

Important:
If you are unsure about operating any device with the Freedom
HF, contact the manufacturer of the device to ensure that it is compatible with the
modified sine waveform.
