Environmental confirmation
The following points must also be confirmed before the actual installation and use of the inverter:
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. When the altitude exceeds 1000m, please derate 1% of the 100m derating; 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.
5. Is there any direct sunlight or external biological invasion in the actual use environment of the inverter? If so, add extra protection.
6. Is there dust, explosive and flammable gas in the actual use environment of the inverter? If so, add extra protection
