The first step is to check whether the appearance of the inverter is defective, including whether the indicator light is in normal operation, whether the mission control function of the operation panel is complete, and carefully observe the appearance of the inverter under the operating condition, and do the corresponding recording operation; When repairing the inverter, check whether the voltage value and current value exceed the promised value range to prevent the inverter from overloading; If an abnormal situation is found, useful measures should be taken to prevent the problem from expanding, and the inverter problem should be quickly eliminated within the smallest range as far as possible.
The second step is to check whether the power supply equipment is operating normally and whether the fundamental line is damaged when repairing the inverter, so as to ensure that the line operation is always in a stable state; Check whether the cooling mechanism itself and its operation are safe and reliable, and whether the inverter is affected by grease and dust during operation. If too much grease and dust accumulate, it will directly block the operation of the air cooler, resulting in the deviation of the heat dissipation effect of the inverter, resulting in an abnormal increase in the temperature of the inverter, and causing the operation of the inverter. Therefore, it is necessary for the inverter to regularly clean the dust and oil around the cooler to ensure the smooth exhaust of the cooler.
The third step is to detect the heat dissipation and thermal conductivity of the inverter under the operating condition when the inverter is repaired, check whether the radiator is operating normally, do a good job in the daily maintenance of the radiator, sort out the dust on the radiator, and prevent the heat dissipation function of the inverter from being affected by dust accumulation; When installing the inverter, it is necessary to install it in accordance with the relevant specifications, select the device in the area of a good operating environment, eliminate the bad influence of the harsh environment on the operation of the inverter, and especially prevent the inverter from being installed in an environment with dusty, humid and corrosive substances.

Protection function of the Reynolds soft starter
1. Overload protection function: The soft starter introduces a current control loop, so that the change of motor current can be tracked and detected at any time. By increasing the setting of overload current and the anti-time control mode, the overload protection function is realized, so that when the motor is overloaded, the thyristor is turned off and an alarm signal is issued.

Inverter installation and heat dissipation treatment - Reynolds
The inverter has power loss during operation and converts it into heat energy, which increases its own temperature. Roughly speaking, the power loss of every 1kVA inverter capacity is about 40W-50W. Therefore, when installing the inverter, it is necessary to consider the heat dissipation of the inverter, and how to run the inverter.
