Operating During Transition Between Shore Power and Inverter Mode
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 charger temperature starts to approach its limit, the charging current will be reduced to 10 amps (Freedom HF 1000 models) or 20 amps (Freedom HF 1500/1800 models).
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 . See “To reset error codes to :” on page 37.
Trouble Loads
EQUIPMENT DAMAGE
Some equipment may be damaged by the Freedom HF’s modified sine wave output, which has a different wave form than utility- supplied electricity.
Failure to follow these instructions can damage the unit and/or damage other equipment.
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 viii for details.
• Metal halide arc (HMI) lights can be damaged.
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.
