1. Does the ambient temperature of the inverter exceed 40°C? If exceeded, derate by 1% for every 1°C increase. Also, do not use the drive in environments above 50°C.
Note: For the use of frequency converters for cabinet loading, the ambient temperature is the air temperature inside the cabinet.
2. Is the actual ambient temperature of the inverter lower than -10°C? If it is below -10°C, increase the heating facility.
Note: For the use of frequency converters for cabinet loading, the ambient temperature is the air temperature inside the cabinet.
3. Is the altitude of the place where the inverter is actually used more than 1000m? If exceeded, derate by 1% for every 100m of elevation. When the altitude exceeds 3000m, please contact your local INVT dealer or office for more information.
4. Does the humidity of the actual use environment of the inverter exceed 90%? Is there condensation? If so, add extra protection.
