Operating environment
The Clean Power VFDs are manufactured with various precision electronic components.
Therefore the installation environment can impact the lifespan and reliability of the product.
The information below describes the recommended operation and installation conditions for the Clean Power VFD.
The user must comply with the environmental conditions listed below in order to ensure that the Clean Power VFD operates safely and correctly.
Failure to adhere to these environmental conditions may shorten the lifespan of the device, lead to malfunctioning and device failure, and void the warranty.
Environment | Conditions |
|---|---|
Installation area | The Clean Power VFD must be mounted in a well ventilated electrical cabinet respecting the clearance distances described in this document. |
Ambient temperature | The normal operating range of the Clean Power VFD is -15 to 50℃ (without derating) If the ambient operating temperature is higher than 50 ℃, the Clean Power VFD must be derated and the ventilation and heat dissipation must be enhanced. The reliability of the Clean Power VFD increases in environments where temperature fluctuations are limited. When using an enclosure, install a cooling fan or air conditioner in the area to ensure the air temperature inside the housing does not exceed the specified levels. Do not allow ice to form on the frequency converter. |
Relative humidity | Below 95% non-condensing. |
Surrounding environment pollution degree | 2, conforming to IEC61800-5-1 |
Storage temperature | -40...70 °C |
Surrounding area | Mount in an area free of: -oil mist and dust -metal shavings, oil, water or other foreign materials -radioactive materials -combustible materials -toxic or corrosive gases and liquids -excessive vibration -chlorides -direct sunlight -EMI source and other electronic devices that are sensitive to EMI |
Altitude | Lower than 2000 m/6600 ft. Contact SmartD Technologies Inc. if you intend to use the Clean Power VFD at higher altitude. |
Vibrations | Mount in a location where vibrations are less than an amplitude of 1.5 mm peak to peak (f= 2...13 Hz) and acceleration lower than 1 gn (f= 13...200 Hz). |
Best practices:⚓
To prevent high surrounding air temperature, users should design their electrical panel following the listed best practices:
No heat stagnation in the panel.
Sufficient heat dissipation of the panel (Size not too small, proper ventilation).
Ventilation slits of the Clean Power VFD are not blocked by any object such as cable or cable trays.
Avoid the proximity of any exothermic device.
Ensure the mounting orientation of the Clean Power VFD allows an optimized airflow.
Respect the clearance distances.
