successfully, release the key; you can observe the working condition of the machine from the panel. When the inverter gives an alarm or enters the protection state, after eliminating the cause of the fault, just restart the machine to resume normal operation; if it is necessary to shut down, when the machine is in the normal working state, long press the "on/off" key for about six seconds until the LCD displays"The system has been shut down, please press the start button", indicating that the shutdown is successful. If you want to close a single module, please pull the snap switch of the module.
11 Maintenance guide 11.1 Maintenance guide Correct maintenance includes preventive maintenance and remedial maintenance. Correct maintenance is the key to the optimal operation of the inverter and will ensure a long service life of the equipment. Preventive maintenance includes frequently executed procedures to prevent power system failure and maximize operation efficiency. Remedial maintenance includes finding faults in the power system for effective maintenance.
11.2 Safety precautions In order to carry out the maintenance of the power supply system safely and successfully, we must abide by the relevant safety prevention knowledge, use the necessary tools and test equipment, and have qualified maintenance personnel participate. We must always pay attention to the following safety operation procedures: 1) It must be kept in mind that even if the inverter system is not running, there is still dangerous voltage inside the inverter. After the input is disconnected, there may be unfinished charge on the bus of the internal large electrolytic capacitor. Internal maintenance can only be carried out after the capacitor of the inverter bus is discharged.
Check with a voltmeter before maintenance to ensure that the power supply is turned off and safeFull state. 2) When operating the inverter, do not wear conductive objects such as rings and watches. 3) Don't take safe operation for granted. If you have any questions, please consult personnel familiar with the equipment. 21
