Xantrex Technology HF 1000, HF 1800 manual Trouble Loads, Over-temperature Conditions

Trouble Loads

CAUTION

Some equipment may be damaged by the Freedom HF’s modified sine wave output, which has a different wave form than utility-supplied electricity.

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 ix 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.

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 charger 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.
