One of the ten "tortures" of frequency converters : Loading
Prolonged overloading will not only affect the lifespan of the motor, but will also damage your frequency converter and shorten its service life.
The second of the ten "tortures" in inverters: sauna
The ambient temperature is too high, the fan is stuck, the temperature sensor is malfunctioning, and the motor is overheating. The inverter is never maintained; inverters also require frequent, periodic maintenance and upkeep.
The third of the ten "tortures" in inverters: undervoltage
Insufficient power supply voltage or generator voltage can cause frequent undervoltage in the frequency converter, which can easily lead to damage to internal components!
The fourth of the ten "tortures" in inverters: being rained on.
Before the inverter is installed and commissioned, it is in a humid environment; after the inverter is in operation, the working environment is relatively harsh, with rainwater entering the inverter from time to time. The electrical components of the inverter are in a humid environment for a long time, which is very detrimental to its circuit board.
The fifth of the ten "tortures" in inverters: Lightning strikes
The inverter was not grounded or equipped with lightning protection measures as required by the equipment manufacturer, which makes it prone to damage during thunderstorms.
The sixth of the ten "tortures" of frequency converters: overvoltage
Excessive power supply voltage or generator voltage, or prolonged high power supply to the frequency converter, can easily damage internal components!
The seventh of the ten "tortures" of frequency converters: corrosion
Corrosive gases can cause poor contact in toggle switches and relays, short circuits between crystals, short circuits in the main circuit due to terminal corrosion, and short circuits between components due to circuit board corrosion.
The eighth of the ten "tortures" in inverters: trampoline
If all frequency converters are installed on the same rigid foundation, or if the foundation is too weak and cannot provide sufficient strength, the frequency converters will vibrate and bounce around like they are on a trampoline.
The ninth of the ten "tortures" in inverters: Cold violence
Inverters never receive enough "care." Users do not check and maintain inverters according to the manufacturer's requirements, or do not replace fans for many years, do not blow dust off the inverters, and do not check for loose screws, causing inverters to go from "minor problems left untreated" to "major problems that cannot be cured."
The tenth of the ten "tortures" in inverters: A small horse pulling a cart
Inaccurate selection can cause inverter overload, resulting in a situation where the inverter is underpowered and the parameters are not adjusted to the optimal operating conditions. This can lead to frequent overcurrent and overvoltage tripping of the inverter's protection mechanisms, causing premature wear and damage.
