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
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.
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.
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.
