increment of one degree Celsius. Also, forced external heat dissipation must be provided.
2) At 1,000m above sea level, the thinner air will deteriorate the heat dissipation effect of the
inverter. Therefore, the inverter must be derated by 1% for every increment of 100m.
3) When the set carrier frequency exceeds the factory settings, the inverter must be derated by 5%
for every increment of 1kHz.
