1. Capable of operating at 73% of rated full load for up to 2 hours at 74°C. Above 55°C ambient, derate output power by 1.4% per °C rise,
up to 74°C max.
2. Capable of operating at 100% of rated full load below 0°C down to -40°C after the Alpha FXM has been stabilized at 0°C for at least 1
hour.
3. FXM 1100/2000-120V only: above 50°C ambient, derate output power by 1.1% per °C rise, up to 74°C max.
4. Derate 2°C per 300 m (1000 ft) above 1400 m (4500 ft).
5. For FXM650/1100-48(Q), the default setting of C3 is “FAULT”.
6. The LCD display may not function below -15°C. It gradually resumes normal operation as the temperature rises above -15°C. This will not
affect the operation of the Alpha FXM.
