Selection of SN200MN frequency inverter
1. Places of use: Indoor, free from sunlight, no dust, corrosive gases, flammable gasses, oil mist, water vapor, drip or salt, etc.
2. Lower than 1000 meters.
3. -10℃~+40℃(Derated if used at the ambient temperature of 40℃-50℃)
4. Less than 5. 9m/s2(0. 6g)
1. Insulation inspection of motor :
When firstly using motor, using motor again after putting for a long time and regularly checking motor winding. During insulation inspection, separate motor wire from frequency converter. 500V voltage-type tramegger is suggested and ensure measured insulation resistance >5MΩ.
2. Thermal protection of motor:
If selected motor does not match with rated capacity of frequency converter, especially if rated power is larger than that of frequency converter, please adjust related parameter values of motor protection or install thermal relay in front of motor for protection.
3. Operation above power frequency:
The frequency converter offers output frequency at 0Hz~3200Hz. If users need to operate at above 50Hz, please consider the tolerance of mechanical device.
4. Lightening impulse protection:
There's lightening stroke over-current protection device in frequency converter, so it has certain self-protection ability for inductive thunder. If lightening stoke is frequent in the place of client, additional protection in front of frequency converter is essential.
