Inverter Loads

Trouble Loads
Some appliances, including the types listed below, may be damaged if
they are connected to the Freedom HW:
• 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 ix for
details.
• Metal halide arc (HMI) lights can be damaged.
Over-temperature Conditions
During Inverter mode, when the Freedom HW’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 HW will recover automatically and will continue inverting.
During AC shore power mode, when the Freedom HW’s charger
temperature starts to approach its threshold limit, the charging current will
automatically derate from 55 A to 35 A. If the temperature continues to
rise, the unit will shut down and resume operation when the unit
temperature has cooled down.
The Freedom HW 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.
CAUTION
Some equipment may be damaged by the Freedom HW’s modified sine wave
output, which has a different wave form than utility-supplied electricity.
Important:
If you are unsure about operating any device with the Freedom
HW, contact the manufacturer of the device to ensure that it is compatible with
the modified sine waveform.
